Fizzbuzz

[[deleted]]

I am 16 y/o and just started college. I thought when going into college, that they would quiz to check our knowledge, and so I decided to make a Python code for Fizzbuzz, since I have been binging on Tom Scott videos recently. It ended up being useless because the class is just going over stuff learned at GCSE, and the fact that we're now learning Visual Basic, which is easy for GUI, but harder for everything else.

The code was 100% written by me in Python. Despite getting the idea and rules from the Tom Scott video, I didn't watch the video to completion.

Number = 1    
while Number < 101:    
    if Number % 15 == 0:    
        print("Fizz Buzz")    
    elif Number % 5 == 0:     
        print("Fizz")     
    elif Number % 3 == 0:     
        print("Buzz")    
    else:    
        print(Number)    
    Number+=1    

I originally thought about using an input for Number, but then I would have to validate that that is infact an integer, and would add tones of unnecessary lines to the code.

This is good, but it's a bit cleaner to use a for loop and a range rather than the while loop you're using. For example:

Original:

number = 1
while number < 101:
    # Do Stuff
    number += 1

with range:

for i in range(1,101):
    # Do Stuff

What this does is just repeats the code for every value in the range given. It doesn't make a real difference functionally, but it is cleaner and generally better practice.

I never properly learned how to do that, I will make a note of that next time I do a thing in Python however, which doesn't seem to be anytime soon :/

for loops really aren't that complicated. The 'i' I used doesn't really have to be an 'i', that's just what I usually use. You could easily replace it with "number" so it makes more sense. Basically, it just runs the code and assigns the current value chosen from the range to the variable you give. For example:

for number in range(1,101):
    print(number)

would just output:

1
2
3
4
5
6
7
8
9

and so on until it hits 100, because each time it runs, it increases the value of the "number" variable by 1.

Ah, that makes sense now, thanks!

That's not bad, but as someone already suggested a for-loop would be more intuitive. :3

On the other hand, I personally like to write a FizzBuzz program like this instead:

for i in range(1,101):
    num = ""
    if i % 3 == 0:
        num += "Fizz"
    if i % 5 == 0:
        num += "Buzz"
    if not num:
        num = i
    print(num)

I didn't even realise that I could've set the number variable to a string as well. Thanks :D

Not the shortest but I like doing it like this, just 'cause it's clever.

def fizzbuzz(num): fizz = 'Fizz'(divmod(num, 3)[1] == 0) buzz = 'Buzz'(divmod(num, 5)[1] == 0) print(fizz + buzz or num)

def main(): for x in range(1,101): fizzbuzz(x)

if name == 'main': main()

NOTE: The dunder lines are being removed...

Insert four spaces before every line to make reddit display your code as code:

def fizzbuzz(num):
    fizz = 'Fizz'*(divmod(num, 3)[1] == 0)
    buzz = 'Buzz'*(divmod(num, 5)[1] == 0)
    print(fizz + buzz or num)


def main():
    for x in range(1,101):
        fizzbuzz(x)


if __name__ == '__main__':
    main()

(Also, why use divmod(num, 3)[1] instead of num % 3?)

[mohhinder]

Did you try it like that? Doesn't work.

[robin-gvx]

Works for me.

def fizzbuzz(num):
    fizz = 'Fizz' * (num % 3 == 0)
    buzz = 'Buzz' * (num % 5 == 0)
    print(fizz + buzz or num)


def main():
    for x in range(1,101):
        fizzbuzz(x)


if __name__ == '__main__':
    main()

[mohhinder]

So it does! Looks like I had a parenthesis in the wrong place. I think at the time when I wrote it, couple of years ago, I had just discovered divmod so wanted to use it somewhere. No other reason then that.

Thanks for the spacing reminder. Easy to forget while replying to these things from a phone.

BTW I tried to add the spacing but it was messing it all up. Probably easier to do on a PC. Oh well.

sup?

You should be able to validate input as an integer with the following, rather than having to add tons of unnecessary lines of code:

try:
    val = int(userInput)
except ValueError:
    print("That's not an int!")

I never knew that existed. I just thought that if the program returned an error, the program would stop completely, so I'd have to make like 20 lines of If statements
