[Python-modules-team] Bug#896403: python-fake-factory: faker fails to import

[Helmut Grohne]

Package: python-fake-factory
Version: 0.7.7-2
Severity: serious
User: helmutg at debian.org
Usertags: python-import

After installing python-fake-factory importing the module faker
into a python interpreter fails with the following error:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/faker/__init__.py", line 4, in <module>
    from faker.factory import Factory
  File "/usr/lib/python2.7/dist-packages/faker/factory.py", line 10, in <module>
    from faker.config import DEFAULT_LOCALE, PROVIDERS, AVAILABLE_LOCALES
  File "/usr/lib/python2.7/dist-packages/faker/config.py", line 13, in <module>
    AVAILABLE_LOCALES = find_available_locales(PROVIDERS)
  File "/usr/lib/python2.7/dist-packages/faker/utils/loading.py", line 19, in find_available_locales
    provider_module = import_module(provider_path)
  File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module
    __import__(name)
  File "/usr/lib/python2.7/dist-packages/faker/providers/internet/__init__.py", line 5, in <module>
    from ipaddress import ip_address, ip_network, IPV4LENGTH, IPV6LENGTH
ImportError: No module named ipaddress

The vast majority of import failures is attributed to missing dependencies.
Often times that manifests as an ImportError or ModuleNotFoundError.
Typically, dependencies should be inserted by dh-python via ${python:Depends}
or ${python3:Depends}. Thus a missing dependency can be caused by incomplete
install_requires in setup.py. Sometimes a missing dependency of a dependency
is the cause, in such cases this bug should be reassigned.
