This module has no docstring.
Compatibility add-in for mapping to indicate that
mapping behavior is deprecated.

Allow an otherwise immutable object to implement mutability
for compatibility.

append(self, *args, **kwargs)
clear(self, /) Remove all items from list.
copy(self, /) Return a shallow copy of the list.
count(self, value, /) Return number of occurrences of value.
extend(self, *args, **kwargs)
index(self, value, start=0, stop=9223372036854775807, /) Return first index of value. Raises ValueError if the value is not present.
insert(self, *args, **kwargs)
pop(self, *args, **kwargs)
remove(self, *args, **kwargs)
reverse(self, *args, **kwargs)
sort(self, *args, **kwargs)
A Python distribution package.
at(path)
Return a Distribution for the indicated metadata path
:param path: a string or path-like object
:return: a concrete Distribution instance for the path
discover(**kwargs)
Return an iterable of Distribution objects for all packages.
Pass a ``context`` or pass keyword arguments for constructing
a context.
:context: A ``DistributionFinder.Context`` object.
:return: Iterable of Distribution objects for all packages.
from_name(name)
Return the Distribution for the given package name.
:param name: The name of the distribution package to search for.
:return: The Distribution instance (or subclass thereof) for the named
package, if found.
:raises PackageNotFoundError: When the named package's distribution
metadata cannot be found.
locate_file(self, path)
Given a path to a file in this distribution, return a path
to it.
read_text(self, filename)
Attempt to load metadata file given by the name.
:param filename: The name of the file in the distribution info.
:return: The text if found, otherwise None.
entry_points = <property object at 0x7f75e2b313f0>
files = <property object at 0x7f75e2b31440>
Files in this distribution.
:return: List of PackagePath for this distribution or None
Result is `None` if the metadata file that enumerates files
(i.e. RECORD for dist-info or SOURCES.txt for egg-info) is
missing.
Result may be empty if the metadata exists but is empty.
metadata = <property object at 0x7f75e2b312b0>
Return the parsed metadata for this Distribution.
The returned object will have keys that name the various bits of
metadata. See PEP 566 for details.
name = <property object at 0x7f75e2b31300> Return the 'Name' metadata for the distribution package.
requires = <property object at 0x7f75e2b31490> Generated requirements specified for this Distribution
version = <property object at 0x7f75e2b313a0> Return the 'Version' metadata for the distribution package.
A MetaPathFinder capable of discovering installed distributions.
Keyword arguments presented by the caller to
``distributions()`` or ``Distribution.discover()``
to narrow the scope of a search for distributions
in all DistributionFinders.
Each DistributionFinder may expect any parameters
and should attempt to honor the canonical
parameters defined below when appropriate.
name = None
path = <property object at 0x7f75e2b31530>
The sequence of directory path that a distribution finder
should search.
Typically refers to Python installed package paths such as
"site-packages" directories and defaults to ``sys.path``.
find_distributions(self, context=<importlib.metadata.DistributionFinder.Context object at 0x7f75e2b0f8e0>)
Find distributions.
Return an iterable of all Distribution instances capable of
loading the metadata for packages matching the ``context``,
a DistributionFinder.Context instance.
find_module(self, fullname, path)
Return a loader for the module.
If no module is found, return None. The fullname is a str and
the path is a list of strings or None.
This method is deprecated since Python 3.4 in favor of
finder.find_spec(). If find_spec() exists then backwards-compatible
functionality is provided for this method.
invalidate_caches(self)
An optional method for clearing the finder's cache, if any.
This method is used by importlib.invalidate_caches().
An entry point as defined by Python packaging conventions.
See `the packaging docs on entry points
<https://packaging.python.org/specifications/entry-points/>`_
for more information.
>>> ep = EntryPoint(
... name=None, group=None, value='package.module:attr [extra1, extra2]')
>>> ep.module
'package.module'
>>> ep.attr
'attr'
>>> ep.extras
['extra1', 'extra2']
count(self, value, /) Return number of occurrences of value.
index(self, value, start=0, stop=9223372036854775807, /) Return first index of value. Raises ValueError if the value is not present.
load(self)
Load the entry point from its definition. If only a module
is indicated by the value, return that module. Otherwise,
return the named object.
matches(self, **params)
EntryPoint matches the given parameters.
>>> ep = EntryPoint(group='foo', name='bar', value='bing:bong [extra1, extra2]')
>>> ep.matches(group='foo')
True
>>> ep.matches(name='bar', value='bing:bong [extra1, extra2]')
True
>>> ep.matches(group='foo', name='other')
False
>>> ep.matches()
True
>>> ep.matches(extras=['extra1', 'extra2'])
True
>>> ep.matches(module='bing')
True
>>> ep.matches(attr='bong')
True
