[Python-modules-team] Bug#896390: python3-pip: pip fails to import

[Helmut Grohne]

Package: python3-pip
Version: 9.0.1-2
Severity: serious
User: helmutg at debian.org
Usertags: python-import

After installing python3-pip importing the module pip
into a python interpreter fails with the following error:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/pip/__init__.py", line 26, in <module>
    from pip.utils import get_installed_distributions, get_prog
  File "/usr/lib/python3/dist-packages/pip/utils/__init__.py", line 23, in <module>
    from pip.locations import (
  File "/usr/lib/python3/dist-packages/pip/locations.py", line 9, in <module>
    from distutils import sysconfig
ImportError: cannot import name 'sysconfig'

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.
