New submission from Michael Hipp <[email protected]>:
A local *unexecuted* import appears to be changing the namespace. Attached
files are ready to run.
# over.py
SOMETHING = "overridden"
# main.py
OVERRIDE = False
SOMETHING = "original"
def main():
#global SOMETHING # uncomment and it works
if OVERRIDE:
from over import SOMETHING # comment out and it works
pass
print SOMETHING # UnboundLocalError: local variable 'SOMETHING' referenced
before assignment
The SOMETHING variable has a value from the module global namespace, but it
gets lost due to an import that is never executed.
I would think an unexecuted statement shouldn't have any effect on anything.
The second file will have to be submitted in a follow-on, it appears
