    string = string + str(num)
    print (string)
 
print FizzBuzz(raw_input())

Answer 1

You have not used proper intendation in the code.

   print FizzBuzz(raw_input())

This statement doesn't print anything because the FizzBuzz function is not returning any value to the function call. (None is taken as return value)

def FizzBuzz(num):
    for num in range (1,50):
        string = ""
        if num % 3 == 0:
            string = string + "Fizz"
        if num % 5 == 0:
            string = string + "Buzz"
        if num % 5 != 0 and  num % 3 != 0:
            string = string + str(num)
        print (string)
FizzBuzz(raw_input()) # function call (no need to use print statement as nothing is returned```
