class int(object)
| int([x]) -> integer
| int(x, base=10) -> integer
|
| Convert a number or string to an integer, or return 0 if no arguments
| are given. If x is a number, return x.__int__(). For floating-point
| numbers, this truncates towards zero.
|
| If x is not a number or if base is given, then x must be a string,
| bytes, or bytearray instance representing an integer literal in the
| given base. The literal can be preceded by '+' or '-' and be surrounded
| by whitespace. The base defaults to 10. Valid bases are 0 and 2-36.
| Base 0 means to interpret the base from the string as an integer literal.
| >>> int('0b100', base=0)

base64.a85decode
Python Library Documentation: function a85decode in module base64
a85decode(b, *, foldspaces=False, adobe=False, ignorechars=b' \t\n\r\x0b')
Decode the Ascii85 encoded bytes-like object or ASCII string b.
foldspaces is a flag that specifies whether the 'y' short sequence should be
accepted as shorthand for 4 consecutive spaces (ASCII 0x20). This feature is
not supported by the "standard" Adobe encoding.
adobe controls whether the input sequence is in Adobe Ascii85 format (i.e.
is framed with <~ and ~>).
ignorechars should be a byte string containing characters to ignore from the
input. This should only contain whitespace characters, and by default
contains all whitespace characters in ASCII.
The result is returned as a bytes object.
base64.a85encode
Python Library Documentation: function a85encode in module base64
a85encode(b, *, foldspaces=False, wrapcol=0, pad=False, adobe=False)
Encode bytes-like object b using Ascii85 and return a bytes object.
foldspaces is an optional flag that uses the special short sequence 'y'
instead of 4 consecutive spaces (ASCII 0x20) as supported by 'btoa'. This
feature is not supported by the "standard" Adobe encoding.
wrapcol controls whether the output should have newline (b'\n') characters
added to it. If this is non-zero, each output line will be at most this
many characters long, excluding the trailing newline.
pad controls whether the input is padded to a multiple of 4 before
encoding. Note that the btoa implementation always pads.
adobe controls whether the encoded byte sequence is framed with <~ and ~>,
which is used by the Adobe implementation.
base64.b16decode
Python Library Documentation: function b16decode in module base64
b16decode(s, casefold=False)
Decode the Base16 encoded bytes-like object or ASCII string s.
Optional casefold is a flag specifying whether a lowercase alphabet is
acceptable as input. For security purposes, the default is False.
The result is returned as a bytes object. A binascii.Error is raised if
s is incorrectly padded or if there are non-alphabet characters present
in the input.
base64.b16encode
Python Library Documentation: function b16encode in module base64
b16encode(s)
Encode the bytes-like object s using Base16 and return a bytes object.
base64.b32decode
Python Library Documentation: function b32decode in module base64
b32decode(s, casefold=False, map01=None)
Decode the base32 encoded bytes-like object or ASCII string s.
Optional casefold is a flag specifying whether a lowercase alphabet is
acceptable as input. For security purposes, the default is False.
RFC 3548 allows for optional mapping of the digit 0 (zero) to the
letter O (oh), and for optional mapping of the digit 1 (one) to
either the letter I (eye) or letter L (el). The optional argument
map01 when not None, specifies which letter the digit 1 should be
mapped to (when map01 is not None, the digit 0 is always mapped to
the letter O). For security purposes the default is None, so that
0 and 1 are not allowed in the input.
The result is returned as a bytes object. A binascii.Error is raised if
the input is incorrectly padded or if there are non-alphabet
characters present in the input.
base64.b32encode
Python Library Documentation: function b32encode in module base64
b32encode(s)
Encode the bytes-like objects using base32 and return a bytes object.
base64.b32hexdecode
Python Library Documentation: function b32hexdecode in module base64
b32hexdecode(s, casefold=False)
Decode the base32hex encoded bytes-like object or ASCII string s.
Optional casefold is a flag specifying whether a lowercase alphabet is
acceptable as input. For security purposes, the default is False.
The result is returned as a bytes object. A binascii.Error is raised if
the input is incorrectly padded or if there are non-alphabet
characters present in the input.
base64.b32hexencode
Python Library Documentation: function b32hexencode in module base64
b32hexencode(s)
Encode the bytes-like objects using base32hex and return a bytes object.
base64.b64decode
Python Library Documentation: function b64decode in module base64
b64decode(s, altchars=None, validate=False)
Decode the Base64 encoded bytes-like object or ASCII string s.
Optional altchars must be a bytes-like object or ASCII string of length 2
which specifies the alternative alphabet used instead of the '+' and '/'
characters.
The result is returned as a bytes object. A binascii.Error is raised if
s is incorrectly padded.
If validate is False (the default), characters that are neither in the
normal base-64 alphabet nor the alternative alphabet are discarded prior
to the padding check. If validate is True, these non-alphabet characters
in the input result in a binascii.Error.
For more information about the strict base64 check, see:
https://docs.python.org/3.11/library/binascii.html#binascii.a2b_base64
base64.b64encode
Python Library Documentation: function b64encode in module base64
b64encode(s, altchars=None)
Encode the bytes-like object s using Base64 and return a bytes object.
Optional altchars should be a byte string of length 2 which specifies an
alternative alphabet for the '+' and '/' characters. This allows an
application to e.g. generate url or filesystem safe Base64 strings.
base64.b85decode
Python Library Documentation: function b85decode in module base64
b85decode(b)
Decode the base85-encoded bytes-like object or ASCII string b
The result is returned as a bytes object.
base64.b85encode
Python Library Documentation: function b85encode in module base64
b85encode(b, pad=False)
Encode bytes-like object b in base85 format and return a bytes object.
If pad is true, the input is padded with b'\0' so its length is a multiple of
4 bytes before encoding.

FUNCTIONS
a2b_base64(data, /, *, strict_mode=False)
Decode a line of base64 data.
strict_mode
When set to True, bytes that are not part of the base64 standard are not allowed.
The same applies to excess data after padding (= / ==).
a2b_hex(hexstr, /)
Binary data of hexadecimal representation.
hexstr must contain an even number of hex digits (upper or lower case).
This function is also available as "unhexlify()".
a2b_qp(data, header=False)
Decode a string of qp-encoded data.
a2b_uu(data, /)
Decode a line of uuencoded data.
b2a_base64(data, /, *, newline=True)
Base64-code line of data.
b2a_hex(...)
Hexadecimal representation of binary data.
sep
An optional single character or byte to separate hex bytes.
bytes_per_sep
How many bytes between separators. Positive values count from the
right, negative values count from the left.
The return value is a bytes object. This function is also
available as "hexlify()".
Example:
>>> binascii.b2a_hex(b'\xb9\x01\xef')
b'b901ef'
>>> binascii.hexlify(b'\xb9\x01\xef', ':')
b'b9:01:ef'
>>> binascii.b2a_hex(b'\xb9\x01\xef', b'_', 2)
b'b9_01ef'
b2a_qp(data, quotetabs=False, istext=True, header=False)
Encode a string using quoted-printable encoding.
On encoding, when istext is set, newlines are not encoded, and white
space at end of lines is. When istext is not set, \r and \n (CR/LF)
are both encoded. When quotetabs is set, space and tabs are encoded.
b2a_uu(data, /, *, backtick=False)
Uuencode line of data.

DESCRIPTION
This module provides regular expression matching operations similar to
those found in Perl. It supports both 8-bit and Unicode strings; both
the pattern and the strings being processed can contain null bytes and
characters outside the US ASCII range.
Regular expressions can contain both special and ordinary characters.
Most ordinary characters, like "A", "a", or "0", are the simplest
regular expressions; they simply match themselves. You can
concatenate ordinary characters, so last matches the string 'last'.
The special characters are:
"." Matches any character except a newline.
"^" Matches the start of the string.
"$" Matches the end of the string or just before the newline at
the end of the string.
"*" Matches 0 or more (greedy) repetitions of the preceding RE.
Greedy means that it will match as many repetitions as possible.
"+" Matches 1 or more (greedy) repetitions of the preceding RE.
"?" Matches 0 or 1 (greedy) of the preceding RE.
*?,+?,?? Non-greedy versions of the previous three special characters.
{m,n} Matches from m to n repetitions of the preceding RE.
{m,n}? Non-greedy version of the above.
"\\" Either escapes special characters or signals a special sequence.
[] Indicates a set of characters.
A "^" as the first character indicates a complementing set.
"|" A|B, creates an RE that will match either A or B.
(...) Matches the RE inside the parentheses.
The contents can be retrieved or matched later in the string.
(?aiLmsux) The letters set the corresponding flags defined below.
(?:...) Non-grouping version of regular parentheses.
(?P<name>...) The substring matched by the group is accessible by name.
(?P=name) Matches the text matched earlier by the group named name.
(?#...) A comment; ignored.
(?=...) Matches if ... matches next, but doesn't consume the string.
(?!...) Matches if ... doesn't match next.
(?<=...) Matches if preceded by ... (must be fixed length).
(?<!...) Matches if not preceded by ... (must be fixed length).
(?(id/name)yes|no) Matches yes pattern if the group with id/name matched,
the (optional) no pattern otherwise.
The special sequences consist of "\\" and a character from the list
below. If the ordinary character is not on the list, then the
resulting RE will match the second character.
\number Matches the contents of the group of the same number.
\A Matches only at the start of the string.
\Z Matches only at the end of the string.
\b Matches the empty string, but only at the start or end of a word.
\B Matches the empty string, but not at the start or end of a word.
\d Matches any decimal digit; equivalent to the set [0-9] in
bytes patterns or string patterns with the ASCII flag.
In string patterns without the ASCII flag, it will match the whole
range of Unicode digits.
\D Matches any non-digit character; equivalent to [^\d].
\s Matches any whitespace character; equivalent to [ \t\n\r\f\v] in
bytes patterns or string patterns with the ASCII flag.
In string patterns without the ASCII flag, it will match the whole
range of Unicode whitespace characters.
\S Matches any non-whitespace character; equivalent to [^\s].
\w Matches any alphanumeric character; equivalent to [a-zA-Z0-9_]
in bytes patterns or string patterns with the ASCII flag.
In string patterns without the ASCII flag, it will match the
range of Unicode alphanumeric characters (letters plus digits
plus underscore).
With LOCALE, it will match the set [0-9_] plus characters defined
as letters for the current locale.
\W Matches the complement of \w.
\\ Matches a literal backslash.
This module exports the following functions:
match Match a regular expression pattern to the beginning of a string.
fullmatch Match a regular expression pattern to all of a string.
search Search a string for the presence of a pattern.
sub Substitute occurrences of a pattern found in a string.
subn Same as sub, but also return the number of substitutions made.
split Split a string by the occurrences of a pattern.
findall Find all occurrences of a pattern in a string.
finditer Return an iterator yielding a Match object for each match.
compile Compile a pattern into a Pattern object.
purge Clear the regular expression cache.
escape Backslash all non-alphanumerics in a string.
Each function other than purge and escape can take an optional 'flags' argument
consisting of one or more of the following module constants, joined by "|".
A, L, and U are mutually exclusive.
A ASCII For string patterns, make \w, \W, \b, \B, \d, \D
match the corresponding ASCII character categories
(rather than the whole Unicode categories, which is the
default).
For bytes patterns, this flag is the only available
behaviour and needn't be specified.
I IGNORECASE Perform case-insensitive matching.
L LOCALE Make \w, \W, \b, \B, dependent on the current locale.
M MULTILINE "^" matches the beginning of lines (after a newline)
as well as the string.
"$" matches the end of lines (before a newline) as well
as the end of the string.
S DOTALL "." matches any character at all, including the newline.
X VERBOSE Ignore whitespace and comments for nicer looking RE's.
U UNICODE For compatibility only. Ignored for string patterns (it
is the default), and forbidden for bytes patterns.
This module also defines an exception 'error'.

FUNCTIONS
compile(pattern, flags=0)
Compile a regular expression pattern, returning a Pattern object.
escape(pattern)
Escape special characters in a string.
findall(pattern, string, flags=0)
Return a list of all non-overlapping matches in the string.
If one or more capturing groups are present in the pattern, return
a list of groups; this will be a list of tuples if the pattern
has more than one group.
Empty matches are included in the result.
finditer(pattern, string, flags=0)
Return an iterator over all non-overlapping matches in the
string. For each match, the iterator returns a Match object.
Empty matches are included in the result.
fullmatch(pattern, string, flags=0)
Try to apply the pattern to all of the string, returning
a Match object, or None if no match was found.
match(pattern, string, flags=0)
Try to apply the pattern at the start of the string, returning
a Match object, or None if no match was found.
purge()
Clear the regular expression caches
search(pattern, string, flags=0)
Scan through string looking for a match to the pattern, returning
a Match object, or None if no match was found.
split(pattern, string, maxsplit=0, flags=0)
Split the source string by the occurrences of the pattern,
returning a list containing the resulting substrings. If
capturing parentheses are used in pattern, then the text of all
groups in the pattern are also returned as part of the resulting
list. If maxsplit is nonzero, at most maxsplit splits occur,
and the remainder of the string is returned as the final element
of the list.
sub(pattern, repl, string, count=0, flags=0)
Return the string obtained by replacing the leftmost
non-overlapping occurrences of the pattern in string by the
replacement repl. repl can be either a string or a callable;
if a string, backslash escapes in it are processed. If it is
a callable, it's passed the Match object and must return
a replacement string to be used.
subn(pattern, repl, string, count=0, flags=0)
Return a 2-tuple containing (new_string, number).
new_string is the string obtained by replacing the leftmost
non-overlapping occurrences of the pattern in the source
string by the replacement repl. number is the number of
substitutions that were made. repl can be either a string or a
callable; if a string, backslash escapes in it are processed.
If it is a callable, it's passed the Match object and must
return a replacement string to be used.
template(pattern, flags=0)
Compile a template pattern, returning a Pattern object, deprecated

DESCRIPTION
Functions to convert between Python values and C structs.
Python bytes objects are used to hold the data representing the C struct
and also as format strings (explained below) to describe the layout of data
in the C struct.
The optional first format char indicates byte order, size and alignment:
@: native order, size & alignment (default)
=: native order, std. size & alignment
<: little-endian, std. size & alignment
>: big-endian, std. size & alignment
!: same as >
The remaining chars indicate types of args and must match exactly;
these can be preceded by a decimal repeat count:
x: pad byte (no data); c:char; b:signed byte; B:unsigned byte;
?: _Bool (requires C99; if not available, char is used instead)
h:short; H:unsigned short; i:int; I:unsigned int;
l:long; L:unsigned long; f:float; d:double; e:half-float.
Special cases (preceding decimal count indicates length):
s:string (array of char); p: pascal string (with count byte).
Special cases (only available in native format):
n:ssize_t; N:size_t;
P:an integer type that is wide enough to hold a pointer.
Special case (not in native mode unless 'long long' in platform C):
q:long long; Q:unsigned long long
Whitespace between formats is ignored.
The variable struct.error is an exception raised on errors.

FUNCTIONS
calcsize(format, /)
Return size in bytes of the struct described by the format string.
iter_unpack(format, buffer, /)
Return an iterator yielding tuples unpacked from the given bytes.
The bytes are unpacked according to the format string, like
a repeated invocation of unpack_from().
Requires that the bytes length be a multiple of the format struct size.
pack(...)
pack(format, v1, v2, ...) -> bytes
Return a bytes object containing the values v1, v2, ... packed according
to the format string. See help(struct) for more on format strings.
pack_into(...)
pack_into(format, buffer, offset, v1, v2, ...)
Pack the values v1, v2, ... according to the format string and write
the packed bytes into the writable buffer buf starting at offset. Note
that the offset is a required argument. See help(struct) for more
on format strings.
unpack(format, buffer, /)
Return a tuple containing values unpacked according to the format string.
The buffer's size in bytes must be calcsize(format).
See help(struct) for more on format strings.
unpack_from(format, /, buffer, offset=0)
Return a tuple containing values unpacked according to the format string.
The buffer's size, minus offset, must be at least calcsize(format).
See help(struct) for more on format strings.

base64.urlsafe_b64decode
Python Library Documentation: function urlsafe_b64decode in module base64
urlsafe_b64decode(s)
Decode bytes using the URL- and filesystem-safe Base64 alphabet.
Argument s is a bytes-like object or ASCII string to decode. The result
is returned as a bytes object. A binascii.Error is raised if the input
is incorrectly padded. Characters that are not in the URL-safe base-64
alphabet, and are not a plus '+' or slash '/', are discarded prior to the
padding check.
The alphabet uses '-' instead of '+' and '_' instead of '/'.
base64.urlsafe_b64encode
Python Library Documentation: function urlsafe_b64encode in module base64
urlsafe_b64encode(s)
Encode bytes using the URL- and filesystem-safe Base64 alphabet.
Argument s is a bytes-like object to encode. The result is returned as a
bytes object. The alphabet uses '-' instead of '+' and '_' instead of
'/'.
