How can I make it into a function?

Question

Hey, This is a game of "4 in a row", using python (No graphics).
The whole code is working well except of the function that checks whenever someone wins.

In the function "check_win()", lines 83-103 & 106-126 : how can i make the part that is inside the 2 nested for-loops (the third one) - a function that will work for both the cases - they are the same - the third loop.

Answer 1

The code below should work. The global declaration permits you to modify variables that are defined outside the function. In this case the code is updating the X and O streak counts, so the function needs to declare those variables as global.

def count_streaks():
global count_streak_X
global count_streak_O
for k in list_of_column:
if k == 'X':
count_streak_X += 1
count_streak_O = 0
check_if_4()
elif k == 'O':
count_streak_O += 1
count_streak_X = 0
check_if_4()
else:
count_streak_X = 0
count_streak_O = 0

Add this function inside the check_win() function, and replace the inline code with the single statement, check_streaks() in both places.

Let us know if it resolves your question.

Brian, thanks for answering, I tried that many times and it's still not working... for some reason - when its separate: its working, and when its a function and you call it where you need to: its not working...
