If anyone can help me that would be great the information about the issue is below the code.

  player1 = ""
  player2 = ""
  turn = ""

    [0, 1, 2],
    [3, 4, 5],
    [6, 7, 8],

    [1, 4, 7],
    [2, 5, 8],
    [0, 4, 8],
    [2, 4, 6]
    ]

This is in a cog and for line 34 "checkWinner" is not defined but I've tried a few things and I cant get it to work. Any ideas. This is a tictac toe game and Im putting it in a cog. The cog is in a class with the name help. This code is python.

CodePudding user response：

Python reads code top to bottom, so in order to use a function, you must define it vertically before it being used.
You need to define Check Winner before the usage.
Move def checkWinner() before the function in which it is being used

CodePudding user response：

It's because the function call is above the function itself, Python reads down the code and when it calls checkWinner, It has yet to see that function.

You can either move the function to the top of the page.

or the more elegant solution is to function most things you can and use this as the bottom of the page which calls to a function at the top of the page.

if __name__ == "__main__":
   # do something here, call a function etc
