Do u know why when i replace 'return' to 'print' , it has ' None'.

Answer 1

you can try this:
instead of printing in the function return the max value.

def max(x, y):
if x >=y:
return x
else:
return y

print(max(6,7))

Answer 2

Every function that doesn't explicitly return something, returns None instead.
