survey

Hello,

thank you for this cool lib. I'm using it in a project now and I noticed that when I was going to write a test and I imported my implementation module, I got an error from survey.

I extracted this to a minimal example showing the problem. Set up dependencies:

$ pip install survey==5.4.2 pytest==8.3.4

Create implementation file project.py:

import survey

nbr = survey.routines.numeric("Enter a number: ", decimal=False)
print(nbr)

Create a test file test_project.py. It can be empty of tests even! The error gets triggered by just the import of the project module:

import project

Now run the test file with pytest and observe the error:

$ pytest test_project.py

Any ideas on how I can fix this, so I can write test for some functions defined in the same module that imports survey?

Thank you! :)
