Comment obtenir une liste d'exceptions intégrées pour python

Étape 1: Créez un fichier python qui ressemble à ceci:

print_exc_tree.py

from __future__ import print_function
import platform


def classtree(cls, depth=0):
    if depth == 0:
        prefix = ''
    else:
        prefix = '.' * (depth * 3) + ' '
    if cls.__name__.lower() == 'error':
        print('{0}{1} ({2})'.format(prefix, cls.__name__, cls))
    else:
        print('{0}{1}'.format(prefix, cls.__name__))
    for subcls in sorted(cls.__subclasses__(), key=lambda c: c.__name__):
        classtree(subcls, depth+1)


if __name__ == '__main__':
    print('Python Version: {0}'.format(platform.python_version()))
    print()
    classtree(BaseException)

Étape 2: Après avoir créé le fichier python ci-dessus, entrez le code suivant à l'invite de commande.

python  print_exc_tree.py

Étape 3: Vous pouvez obtenir une liste des exceptions intégrées de python comme suit:
