DESCRIPTION
This module provides access to some objects used or maintained by the
interpreter and to functions that interact strongly with the interpreter.
Dynamic objects:
argv -- command line arguments; argv[0] is the script pathname if known
path -- module search path; path[0] is the script directory, else ''
modules -- dictionary of loaded modules
displayhook -- called to show results in an interactive session
excepthook -- called to handle any uncaught exception other than SystemExit
To customize printing in an interactive session or to install a custom
top-level exception handler, assign other functions to replace these.
stdin -- standard input file object; used by input()
stdout -- standard output file object; used by print()
stderr -- standard error object; used for error messages
By assigning other file objects (or objects that behave like files)
to these, it is possible to redirect all of the interpreter's I/O.
last_exc - the last uncaught exception
Only available in an interactive session after a
traceback has been printed.
last_type -- type of last uncaught exception
last_value -- value of last uncaught exception
last_traceback -- traceback of last uncaught exception
These three are the (deprecated) legacy representation of last_exc.
Static objects:
builtin_module_names -- tuple of module names built into this interpreter
copyright -- copyright notice pertaining to this interpreter
exec_prefix -- prefix used to find the machine-specific Python library
executable -- absolute path of the executable binary of the Python interpreter
float_info -- a named tuple with information about the float implementation.
float_repr_style -- string indicating the style of repr() output for floats
hash_info -- a named tuple with information about the hash algorithm.
hexversion -- version information encoded as a single integer
implementation -- Python implementation information.
int_info -- a named tuple with information about the int implementation.
maxsize -- the largest supported length of containers.
maxunicode -- the value of the largest Unicode code point
platform -- platform identifier
prefix -- prefix used to find the Python library
thread_info -- a named tuple with information about the thread implementation.
version -- the version of this interpreter as a string
version_info -- version information as a named tuple
dllhandle -- [Windows only] integer handle of the Python DLL
winver -- [Windows only] version number of the Python DLL
_enablelegacywindowsfsencoding -- [Windows only]
__stdin__ -- the original stdin; don't touch!
__stdout__ -- the original stdout; don't touch!
__stderr__ -- the original stderr; don't touch!
__displayhook__ -- the original displayhook; don't touch!
__excepthook__ -- the original excepthook; don't touch!
Functions:
displayhook() -- print an object to the screen, and save it in builtins._
excepthook() -- print an exception and its traceback to sys.stderr
exception() -- return the current thread's active exception
exc_info() -- return information about the current thread's active exception
exit() -- exit the interpreter by raising SystemExit
getdlopenflags() -- returns flags to be used for dlopen() calls
getprofile() -- get the global profiling function
getrefcount() -- return the reference count for an object (plus one :-)
getrecursionlimit() -- return the max recursion depth for the interpreter
getsizeof() -- return the size of an object in bytes
gettrace() -- get the global debug tracing function
setdlopenflags() -- set the flags to be used for dlopen() calls
setprofile() -- set the global profiling function
setrecursionlimit() -- set the max recursion depth for the interpreter
settrace() -- set the global debug tracing function
SUBMODULES
monitoring
FUNCTIONS
__breakpointhook__ = breakpointhook(...)
breakpointhook(*args, **kws)
This hook function is called by built-in breakpoint().
__displayhook__ = displayhook(object, /)
Print an object to sys.stdout and also save it in builtins._
__excepthook__ = excepthook(exctype, value, traceback, /)
Handle an exception by displaying it with a traceback on sys.stderr.
__unraisablehook__ = unraisablehook(unraisable, /)
Handle an unraisable exception.
The unraisable argument has the following attributes:
* exc_type: Exception type.
* exc_value: Exception value, can be None.
* exc_traceback: Exception traceback, can be None.
* err_msg: Error message, can be None.
* object: Object causing the exception, can be None.
activate_stack_trampoline(backend, /)
Activate stack profiler trampoline *backend*.
addaudithook(hook)
Adds a new audit hook callback.
audit(...)
audit(event, *args)
Passes the event to any audit hooks that are attached.
breakpointhook(...)
breakpointhook(*args, **kws)
This hook function is called by built-in breakpoint().
call_tracing(func, args, /)
Call func(*args), while tracing is enabled.
The tracing state is saved, and restored afterwards. This is intended
to be called from a debugger from a checkpoint, to recursively debug
some other code.
deactivate_stack_trampoline()
Deactivate the current stack profiler trampoline backend.
If no stack profiler is activated, this function has no effect.
displayhook(object, /)
Print an object to sys.stdout and also save it in builtins._
exc_info()
Return current exception information: (type, value, traceback).
Return information about the most recent exception caught by an except
clause in the current stack frame or in an older stack frame.
excepthook(exctype, value, traceback, /)
Handle an exception by displaying it with a traceback on sys.stderr.
exception()
Return the current exception.
Return the most recent exception caught by an except clause
in the current stack frame or in an older stack frame, or None
if no such exception exists.
exit(status=None, /)
Exit the interpreter by raising SystemExit(status).
If the status is omitted or None, it defaults to zero (i.e., success).
If the status is an integer, it will be used as the system exit status.
If it is another kind of object, it will be printed and the system
exit status will be one (i.e., failure).
get_asyncgen_hooks()
Return the installed asynchronous generators hooks.
This returns a namedtuple of the form (firstiter, finalizer).
get_coroutine_origin_tracking_depth()
Check status of origin tracking for coroutine objects in this thread.
get_int_max_str_digits()
Return the maximum string digits limit for non-binary int<->str conversions.
getallocatedblocks()
Return the number of memory blocks currently allocated.
getdefaultencoding()
Return the current default encoding used by the Unicode implementation.
getfilesystemencodeerrors()
Return the error mode used Unicode to OS filename conversion.
getfilesystemencoding()
Return the encoding used to convert Unicode filenames to OS filenames.
getprofile()
Return the profiling function set with sys.setprofile.
See the profiler chapter in the library manual.
getrecursionlimit()
Return the current value of the recursion limit.
The recursion limit is the maximum depth of the Python interpreter
stack. This limit prevents infinite recursion from causing an overflow
of the C stack and crashing Python.
getrefcount(object, /)
Return the reference count of object.
The count returned is generally one higher than you might expect,
because it includes the (temporary) reference as an argument to
getrefcount().
getsizeof(...)
getsizeof(object [, default]) -> int
Return the size of object in bytes.
getswitchinterval()
Return the current thread switch interval; see sys.setswitchinterval().
gettrace()
Return the global debug tracing function set with sys.settrace.
See the debugger chapter in the library manual.
getunicodeinternedsize()
Return the number of elements of the unicode interned dictionary
getwindowsversion()
Return info about the running version of Windows as a named tuple.
The members are named: major, minor, build, platform, service_pack,
service_pack_major, service_pack_minor, suite_mask, product_type and
platform_version. For backward compatibility, only the first 5 items
are available by indexing. All elements are numbers, except
service_pack and platform_type which are strings, and platform_version
which is a 3-tuple. Platform is always 2. Product_type may be 1 for a
workstation, 2 for a domain controller, 3 for a server.
Platform_version is a 3-tuple containing a version number that is
intended for identifying the OS rather than feature detection.
intern(string, /)
``Intern'' the given string.
This enters the string in the (global) table of interned strings whose
purpose is to speed up dictionary lookups. Return the string itself or
the previously interned string object with the same value.
is_finalizing()
Return True if Python is exiting.
is_stack_trampoline_active()
Return *True* if a stack profiler trampoline is active.
set_asyncgen_hooks(...)
set_asyncgen_hooks([firstiter] [, finalizer])
Set a finalizer for async generators objects.
set_coroutine_origin_tracking_depth(depth)
Enable or disable origin tracking for coroutine objects in this thread.
Coroutine objects will track 'depth' frames of traceback information
about where they came from, available in their cr_origin attribute.
Set a depth of 0 to disable.
set_int_max_str_digits(maxdigits)
Set the maximum string digits limit for non-binary int<->str conversions.
setprofile(...)
setprofile(function)
Set the profiling function. It will be called on each function call
and return. See the profiler chapter in the library manual.
setrecursionlimit(limit, /)
Set the maximum depth of the Python interpreter stack to n.
This limit prevents infinite recursion from causing an overflow of the C
stack and crashing Python. The highest possible limit is platform-
dependent.
setswitchinterval(interval, /)
Set the ideal thread switching delay inside the Python interpreter.
The actual frequency of switching threads can be lower if the
interpreter executes long sequences of uninterruptible code
(this is implementation-specific and workload-dependent).
The parameter must represent the desired switching delay in seconds
A typical value is 0.005 (5 milliseconds).
settrace(...)
settrace(function)
Set the global debug tracing function. It will be called on each
function call. See the debugger chapter in the library manual.
unraisablehook(unraisable, /)
Handle an unraisable exception.
The unraisable argument has the following attributes:
* exc_type: Exception type.
* exc_value: Exception value, can be None.
* exc_traceback: Exception traceback, can be None.
* err_msg: Error message, can be None.
* object: Object causing the exception, can be None.

CLASSES
importlib._abc.Loader(builtins.object)
LazyLoader
class LazyLoader(importlib._abc.Loader)
| LazyLoader(loader)
|
| A loader that creates a module which defers loading until attribute access.
|
| Method resolution order:
| LazyLoader
| importlib._abc.Loader
| builtins.object
|
| Methods defined here:
|
| __init__(self, loader)
| Initialize self. See help(type(self)) for accurate signature.
|
| create_module(self, spec)
| Return a module to initialize and into which to load.
|
| This method should raise ImportError if anything prevents it
| from creating a new module. It may return None to indicate
| that the spec should create the new module.
|
| exec_module(self, module)
| Make the module load lazily.
|
| ----------------------------------------------------------------------
| Class methods defined here:
|
| factory(loader)
| Construct a callable which returns the eager loader made lazy.
|
| ----------------------------------------------------------------------
| Data and other attributes defined here:
|
| __abstractmethods__ = frozenset()
|
| ----------------------------------------------------------------------
| Methods inherited from importlib._abc.Loader:
|
| load_module(self, fullname)
| Return the loaded module.
|
| The module must be added to sys.modules and have import-related
| attributes set properly. The fullname is a str.
|
| ImportError is raised on failure.
|
| This method is deprecated in favor of loader.exec_module(). If
| exec_module() exists then it is used to provide a backwards-compatible
| functionality for this method.
|
| ----------------------------------------------------------------------
| Data descriptors inherited from importlib._abc.Loader:
|
| __dict__
| dictionary for instance variables
|
| __weakref__
| list of weak references to the object
FUNCTIONS
find_spec(name, package=None)
Return the spec for the specified module.
First, sys.modules is checked to see if the module was already imported. If
so, then sys.modules[name].__spec__ is returned. If that happens to be
set to None, then ValueError is raised. If the module is not in
sys.modules, then sys.meta_path is searched for a suitable spec with the
value of 'path' given to the finders. None is returned if no spec could
be found.
If the name is for submodule (contains a dot), the parent module is
automatically imported.
The name and package arguments work the same as importlib.import_module().
In other words, relative module names (with leading dots) work.
resolve_name(name, package)
Resolve a relative module name to an absolute one.
source_hash(source_bytes)
Return the hash of *source_bytes* as used in hash-based pyc files.

NAME
warnings - Python part of the warnings subsystem.
MODULE REFERENCE

The following documentation is automatically generated from the Python
source files. It may be incomplete, incorrect or include features that
are considered implementation detail and may vary between Python
implementations. When in doubt, consult the module reference at the
location listed above.
CLASSES
builtins.object
catch_warnings
class catch_warnings(builtins.object)
| catch_warnings(*, record=False, module=None, action=None, category=<class 'Warning'>, lineno=0, append=False)
|
| A context manager that copies and restores the warnings filter upon
| exiting the context.
|
| The 'record' argument specifies whether warnings should be captured by a
| custom implementation of warnings.showwarning() and be appended to a list
| returned by the context manager. Otherwise None is returned by the context
| manager. The objects appended to the list are arguments whose attributes
| mirror the arguments to showwarning().
|
| The 'module' argument is to specify an alternative module to the module
| named 'warnings' and imported under that name. This argument is only useful
| when testing the warnings module itself.
|
| If the 'action' argument is not None, the remaining arguments are passed
| to warnings.simplefilter() as if it were called immediately on entering the
| context.
|
| Methods defined here:
|
| __enter__(self)
|
| __exit__(self, *exc_info)
|
| __init__(self, *, record=False, module=None, action=None, category=<class 'Warning'>, lineno=0, append=False)
| Specify whether to record warnings and if an alternative module
| should be used other than sys.modules['warnings'].
|
| For compatibility with Python 3.0, please consider all arguments to be
| keyword-only.
|
| __repr__(self)
| Return repr(self).
