Hi,

I evaluate legacy codes in python2 but it is not working as expected

demo.py is as follows

import os
result = os.path.join("/etc", "networks")
print(result)

works in python3

PYTHONHUNTER="Q(module='os')" python3 demo.py

not in python2

PYTHONHUNTER="Q(module='os')" python2 demo.py

Regards,
