Here's one problem. On line five, the variable row is set as a string. On line 103, flip is called with row as one of it’s arguments.

def flip(board, row, col, player, playerOpposite):
   while(row<len(board)-2 or col!=0):

In flip () on line 293 row is tested to be less than len(board) producing the error:

Error:
TypeError: '<' not supported between instances of 'str' and 'int'

Because you're testing the string row against the integer len(board).
