Python Exercises for Beginners: Conditional Statements (if elif else)

Problem 1: FizzBuzz

Problem Statement: Write a program that prints the numbers from 1 to n. But for multiples of 3, print “Fizz” instead of the number, and for the multiples of 5, print “Buzz”. For numbers which are multiples of both 3 and 5, print “FizzBuzz”.

Input:

• The first and only line contains the integer n.

Output:

• Print numbers from 1 to n, replacing multiples of 3 with “Fizz”, multiples of 5 with “Buzz”, and multiples of both with “FizzBuzz”.

Example:

Input:

15

Output:

1
2
Fizz
4
Buzz
Fizz
