Prints Duplicates BuzzFizz game

August 1, 2022

n = 0
toTest = [
    3,
    5,
    7
]
outputCanBe = [
    "Fizz",
    "Buzz",
    "Bizz"
]
outputIndex = 0
iteration = (len(toTest)) 
while n <= 100:
    n += 1
    output = ""
    for num in range(iteration):
        if n%toTest[num] == 0:
            outputIndex = num
            output += outputCanBe[outputIndex]
        else:
            output += str(n)  
        print(output)
        output = ""

So, basically, the issue is, in my for num in range(iteration), I am looping this action to check if the number might also be a multiple of 5 and 7, not just 3. However, this outputs results in numbers that are not multiples of 5 and 7, to print duplicates of themselves such as:

This is undesired, how can I go about fixing this?

>Solution :

Add the "Fizz" "Buzz" "Bizz" if the division is possible, at the end if nothing has been added, it means that you have to print the number itself.

n = 0
toTest = [
    3,
    5,
    7
]
outputCanBe = [
    "Fizz",
    "Buzz",
    "Bizz"
]
outputIndex = 0
iteration = (len(toTest)) 
while n <= 25:
    n += 1
    output = ""
    for num in range(iteration):
        if n%toTest[num] == 0:
            outputIndex = num
            output += outputCanBe[outputIndex]
    if not output:
        print(n)
    else:
        print(output)

EDIT :

Here’s a cleaner and shorter version :

words = {3: "Fizz", 5: "Buzz", 7: "Bizz"}
size = 100
for n in range(size):
    output = ""
    for (numb, word) in words.items():
        if n % numb == 0:
            output += word
    print(n) if not output else print(output)

I used a dictionnary to connect a numb (example : 3) and its word (example : "Fizz").

Doing a for loop is just for shorter code.

The .items() method is meant to unpack the (key,value) of a dictionnary.

Python consider that if a str is empty its bool value is False. If it’s not empty, no matter what it contains it’s True. That’s what the if not ouput is for, to check if output is empty (divided by none of these numbers) or not.
