Here is the error:
Traceback (most recent call last): File "C:/Users/Wattel/Desktop/21 21 21.py", line 177, in main() File "C:/Users/Wattel/Desktop/21 21 21.py", line 167, in main PPOINTS, DPOINTS, PHAND, DHAND = dLoop(PHAND, DHAND, DECK) TypeError: 'NoneType' object is not iterable
I know that it has something to do with this code, but can't figure out what the problem is exactly:
scoreHAND(DHAND) < 18 or scoreHAND(DHAND) < 21 and scoreHAND(DHAND) < scoreHAND(PHAND) or scoreHAND(DHAND) < 21
Here is the rest of my code:
