FizzBuzz Problem using Python

The FizzBuzz problem is a popular coding interview question. Here you need to check if a number is divisible by 3 and 5 and return the output based on some conditions. If you want to know how to solve the FizzBuzz problem, this article is for you. In this article, I will take you through how to solve the FizzBuzz problem using Python.

FizzBuzz Problem

In the FizzBuzz problem, you will be given an integer, and you need to return a string array where:

1. the numbers that are divisible by 3 will be replaced with the word “Fizz”;
2. the numbers that are divisible by 5 will be replaced with the word “Buzz”;
3. and the numbers that are divisible by both 3 and 5 will be replaced by the word “FizzBuzz”;

Below is an example of the input and output of this problem:

• Input: 3 | Output: [“1”, “2”, “Fizz”]
• Input: 5 | Output: [“1”, “2”, “Fizz”, “4”, “Buzz”]

Solving the FizzBuzz Problem using Python

I hope you have understood what the FizzBuzz problem means. Now, below is how you can solve this problem using the Python programming language:

def fizzBuzz(n):
    output = []

    for i in range(1, n + 1):
        if (i % 3) == 0 and (i % 5) == 0:
            output.append("FizzBuzz")
        elif i % 3 == 0:
            output.append("Fizz")
        elif i % 5 == 0:
            output.append("Buzz")
        else:
            output.append(str(i))
    return output

print(fizzBuzz(15))

Output: ['1', '2', 'Fizz', '4', 'Buzz', 'Fizz', '7', '8', 'Fizz', 'Buzz', '11', 'Fizz', '13', '14', 'FizzBuzz']
