TypeError: 'type' object is not subscriptable at a for loop

print(licz)

This is my code, I get this error at line 22:

for i in range[0, n]:

I’ve looked through some other posts with a similar error and I just can’t see what I’m doing wrong. Can anyone try to help me?

>Solution :

You need open and closed parenthesis for range

for i in range(0, n):
