this question is probably so common that it is being asked every other minute but I've tried to look for answers and couldn't find it. Most likely I wasn't able to phrase the question well enough.
Anyway, I'm working on a small text-game and it has variables, for simplicity let's say water = 100. And I have a function that is the main loop. Let's say the code looks something like this:
water = 100
def main():
while True:
water -= 5
print(water)
main()
Of course, when I run this program it tells me that the variable was referenced before assignment. But if I make the variable inside the function then with each iteration of the loop it will reset the variable to the original 100.
So how do I make this work? Thanks!
Use keyword global. In your code declare in function global water before the loop and then your code will work fine.
