Fizz Buzz

In Python, Ruby, Java, JavaScript, and Go

In the below examples I was playing with the languages using a simple method and/or trying to call a method from another method or within a class.

Python

python_fizz_buzz_1.py

def fizzbuzz(n):
    fzbz = []
    for x in range(1, n+1):
        if x % 15 == 0:
            fzbz.append("Fizz Buzz")
        elif x % 3 == 0:
            fzbz.append('Fizz')
        elif x % 5 == 0:
            fzbz.append('Buzz')
        else:
            fzbz.append(str(x))
    return fzbz

def print_fizzbuzz():
    print(', '.join(fizzbuzz(20))
    
print_fizzbuzz()

Python - calling methods

python_fizz_buzz_2.py

def fizz_buzz(num):
  fzbz = []
  for x in range(1,num+1):
    if div_by_fifteen(x) == True:
      fzbz.append("Fizz Buzz")
    elif div_by_three(x):
      fzbz.append("Fizz")
    elif div_by_five(x):
      fzbz.append("Buzz")
    else:
      fzbz.append(str(x))
  for value in fzbz:
    print(value)

def div_by_fifteen(n):
  if n % 15 == 0:  
    return True
def div_by_five(n):
  if n % 5 == 0:
    return True
def div_by_three(n):
  if n % 3 == 0:
    return True

Ruby

ruby_fizz_buzz_1.rb

def fizz_buzz(num)
  fzbz = []
  (1..num).each do |x|
    if x % 15 == 0
      fzbz << "Fizz Buzz"
    elsif x % 3 == 0
      fzbz << "Fizz"
    elsif x % 5 == 0
      fzbz << "Buzz"
    else
      fzbz << x
    end
  end
  fzbz
end

print fizz_buzz(45)

Ruby - in a class & calling methods

ruby_fizz_buzz_2.rb

class FizzBuzz

  def div_by_fifteen(n)
    n % 15 == 0
  end

  def div_by_five(n)
    n % 5 == 0
  end

  def div_by_three(n)
    n % 3 == 0
  end

  def print_fizz_buzz(num)
    fzbz = []
    (1..num).each do |x|
      if div_by_fifteen(x)
        fzbz << "Fizz Buzz"
      elsif div_by_three(x)
        fzbz << "Fizz"
      elsif div_by_five(x)
        fzbz << "Buzz"
      else
        fzbz << x
      end
    end
    fzbz
  end
end

f = FizzBuzz.new
puts f.print_fizz_buzz(45)

I refactored the above code, thinking about naming conventions.

class FizzBuzz

  #dividend / divisor == quotient

  def divide_by(dividend, divisor)
    dividend % divisor == 0
  end

  def print_fizz_buzz(upper_bound)
    fizzbuzz = []
    (1..upper_bound).each do |dividend|
      if divide_by(dividend,15)
        fizzbuzz << "fizz buzz"
      elsif divide_by(dividend,3)
        fizzbuzz << "fizz"
      elsif divide_by(dividend,5)
        fizzbuzz << "buzz"
      else
        fizzbuzz << dividend
      end
    end
    fizzbuzz
  end
end

f = FizzBuzz.new
puts f.print_fizz_buzz(45)

Java

JavaFizzBuzz.java

public class FizzBuzz
{
    public static void main(String[] args)
    {
        for (int i = 1; i < 101; i++)
        {
            if (i % 3 != 0 && i % 5 != 0)
            {
                System.out.print(i);
            }
            else
            {
                if (i % 3 == 0)
                {
                    System.out.print("Fizz");
                }
                if (i % 5 == 0)
                {
                    System.out.print("Buzz");
                }
            }
            System.out.print(' ');
        }
    }
}

	for(var i = 1; i <= 100; i++){
		if(i % 15 === 0){
			print('Fizz Buzz');

        } else if i % 3 == 0 {
