When making a function you need () at the end.
def functioname():
You can pass 'a' inside these parentheses and remove from the first line.
You must call a function otherwise it would never run.
How to call a function? Simply write,
print(functionname())
if 'a' is the parameter inside so u can pass the input like,
print(functionname("habzhshanzbhsjanahshsjah")
You should have RETURNS instead of PRINTS inside ur function, otherwise they can return an output 'None' which u dont want.

Can you please send the code so that I can help you?

Answer 3

to check if a string B is a substring of a string A, use 'if B in A' . so the code will be:

a=input()
b='watch'
c='youtu.be'

def utubeid(sring)
if b in string:
return a[32:]
elif c in string:
return a[17:]

print(utubeid (a))

Answer 4

the problem is that if none of those conditions is satisfied, the return value will be None. you must take this in account.
