Wie erhalte ich eine Liste der auf meinem Computer installierten Python-Module?
Antworten
Zu viele Anzeigen?

Ich verwende normalerweise pip list um eine Liste der Pakete (mit Version) zu erhalten.
Das funktioniert natürlich auch in einer virtuellen Umgebung. Um anzuzeigen, was nur in der virtuellen Umgebung installiert ist (nicht die globalen Pakete), verwenden Sie pip list --local .
Hier ist die Dokumentation mit allen verfügbaren pip list Optionen, mit mehreren guten Beispielen.

Dies wird helfen
Geben Sie im Terminal oder in IPython ein:
help('modules')dann
In [1]: import #import press-TAB

Diese Lösung basiert in erster Linie auf Modulen importlib y pkgutil und arbeiten mit CPython 3.4 und CPython 3.5, haben aber keine Unterstützung für CPython 2.
Erläuterung
sys.builtin_module_names- nennt alle eingebauten Module (siehe meine Antwort aquí )pkgutil.iter_modules()- liefert eine Information über alle verfügbaren Moduleimportlib.util.find_spec()- gibt eine Information über das importierte Modul zurück, falls vorhandenBuiltinImporter- einen Importer für eingebaute Module ( docs )SourceFileLoader- einen Importer für ein Standard-Python-Modul (standardmäßig mit der Erweiterung *.py) ( docs )ExtensionFileLoader- einen Importer für Module wie gemeinsame Bibliothek (geschrieben in C oder C++)
Vollständiger Code
import sys
import os
import shutil
import pkgutil
import importlib
import collections
if sys.version_info.major == 2:
raise NotImplementedError('CPython 2 is not supported yet')
def main():
# name this file (module)
this_module_name = os.path.basename(__file__).rsplit('.')[0]
# dict for loaders with their modules
loaders = collections.OrderedDict()
# names`s of build-in modules
for module_name in sys.builtin_module_names:
# find an information about a module by name
module = importlib.util.find_spec(module_name)
# add a key about a loader in the dict, if not exists yet
if module.loader not in loaders:
loaders[module.loader] = []
# add a name and a location about imported module in the dict
loaders[module.loader].append((module.name, module.origin))
# all available non-build-in modules
for module_name in pkgutil.iter_modules():
# ignore this module
if this_module_name == module_name[1]:
continue
# find an information about a module by name
module = importlib.util.find_spec(module_name[1])

# pretty print
