how to compare a list to a list of lists

[ibreeden]

I get very different messages.

Error:
  File "./forum11.py", line 9
    for i,j,k in wins_list:
    ^
IndentationError: unexpected indent

When I corrected this I get:

Error:
Traceback (most recent call last):
  File "./forum11.py", line 10, in <module>
    if i in player1_pieces and j in player1_pieces and k in player1_pieces: 
NameError: name 'player1_pieces' is not defined

When I corrected that I get:

Output:
no winner
no winner
no winner
no winner
no winner
no winner
no winner
x wins

The message you get assumes you have defined a function. I see no function definition in your code.
