What is wrong with this code?

Question

def decor (func):
def wrapper(*args,**kwargs):
password=input("Password:")
If password=="12345":
print("Access Granted")
func(*args,**kwargs)
else:
print("Access Denied")
return wrapper

@decor
def sum(a,b)
return a+b
print(sum(12,13)

It's printing:
Password:12345
Access Granted
None

I can't understand why it's printing None instead of 25
Can anyone suggest any improvement, or just tell me what is wrong with this code ?

Answer 1

Thanks
return function(*args,**kwargs)
worked

Answer 2

return func(*args, **kwargs)

return "Access Denied"
