python - NameError -- not definied -


main program

second file: winning.py:

error

traceback (most recent call last):   file "c:/python32/rps_project/main.py", line 14, in <module>     rock = r nameerror: name 'r' not defined

i have tried quotation marks , all, , cannot figure out!!! this? please , thank you!

don't take negative comments wrong way. sure mark homework homework , sure paste actual error generated code you've posted. error doesn't match code posted.

you might ask question in calmer-seeming way :)

the problem simple. define globals in main program not in winning.py, lines 

if userinput == rock , computerinput == scissor:     print('you win!  rock crushes scissor!')     win += 1

are going cause nameerrors, because rock, scissor , win not defined. in every module, must either define or import names want use; names not shared between modules automatically -- reason!

i'll save trouble telling you must return value winning.winner -- otherwise, won't output expect.
