nanodjango convert: OSError

[fertek]

Thanks for this great project!

I ran into an error when trying to convert a single file into a full Django project.

If I have import urllib.parse code in my app.py file, command nanodjango convert app.py src --name=demo will result in an error:

Traceback (most recent call last):
  File "demo_path/venv/bin/nanodjango", line 8, in <module>
    sys.exit(invoke())
             ^^^^^^^^

    obj_src = inspect.getsource(obj)

    lines, lnum = getsourcelines(object)

  File "/usr/lib/python3.12/inspect.py", line 1260, in getsourcelines
    lines, lnum = findsource(object)

  File "/usr/lib/python3.12/inspect.py", line 1089, in findsource
    raise OSError('could not get source code')
OSError: could not get source code

If I replace import urllib.parse with from urllib import parse, the conversion works.
