[issue47148] sys.path.append before import the module causing module don't have doc-string?

[Zachary Ware]

Zachary Ware <zachary.ware at gmail.com> added the comment:

I can't reproduce this without the `-OO` option:

-OO    : do -O changes and also discard docstrings; add .opt-2 before
         .pyc extension


Note that I did slightly adjust your `b.py` script to do `print(a.multiply.__doc__)`, but here's what I tried:

~/issue47148_test/parent/another folder $ cat ../a.py 
def multiply():
    """multiply stuff"""
    return 69*420
~/issue47148_test/parent/another folder $ cat b.py 
import sys
sys.path.append('..')
import a
print(a.multiply.__doc__)
~/issue47148_test/parent/another folder $ python b.py 
multiply stuff
~/issue47148_test/parent/another folder $ python -O b.py 
multiply stuff
~/issue47148_test/parent/another folder $ python -OO b.py 
None
