I gave up on trying to learn JavaScript, so instead I made a “game” in Python that detects whether or not the ‘cool’ variable equals infinity.

import math

    if math.isinf(cool):
        print(cool, 'is not a cool number.')
        break
    print(cool, 'is a cool number.')

cool += cool

cool *= 2

How long does it take to finish lol

Also, these might look nicer:

cool += cool

or

cool *= 2

import math
num = 0.01
while True:
    num *= 2
    if math.isinf(num):
        print("Number is no longer cool")
        break
    print(f"Number {num} is a cool number")

what does this do

I am making a 3d zombie survival game called swarm in python.

also does anyone know if pygame is working for me? Everytime I add a script like “import pygame” it gives me errors with the note Invalid syntax. It shows a red line on the first > in the script.

Python ints have infinite precision, so it will never reach infinity.

Nothing has infinite precision in computers. The maximum integer for 64-bit programs is 9,223,372,036,854,775,807 before it would overflow.

Integers (int)
These represent numbers in an unlimited range, subject to available (virtual) memory only.

The variable is a float, so it will max out around 10^308 ish. I’m not sure if it will turn into infinity at that point or give an overflow error. I suspect the latter, but I’m not sure.

who else here uses flask on a daily basis

i use it to run my html files on a server that other computers in my house can access (ip stuff idk i don't quite understand it) so i can show people like my dad or my sister what i do in my free time

i also use ngrok (port forwarding service) to put them online but nobody i send the urls to clicks on them (maybe because they look like this: v5ut5e8uj8gusjivjv8tkiyrejb.ngrok.free)


also i made a sort of web hosting site with it where you can post one-file html pages (with no size limit; so my computer's hard drive cried whenever i ran it) and shared it with all my friends

i can post the source if anybody wants to but whatever

tl;dr flask is super flipin kewl
