Why doesn't my code display?

Hello, this is my first attempt at coding. I tried to run it but it wouldn't display?

you never call the 'main()' function.

You'll want to make the last lines of your code:

if __name__ == "__main__":
    main()

That should do it, provided the rest of your code is correct.

Thank you so much!

This is unrelated to your problem, but I saw you wrote out all the colors your self and I feel bad so here's a little something I made for you and anyone else to use. Thank me later. (btw use it by doing something like "bgColor = color.light_green")

import random

class colour:
  #Common colours

  #green
  light_green = (0, 252, 0)
  dark_green = (0, 58, 18)
  green = (5, 191, 24)

  #blue
  light_blue = (2, 162, 255)
  dark_blue = (0, 46, 73)
  blue = (5, 123, 191)

  #red
  light_red = (249, 2, 23)
  dark_red = (104, 1, 9)
  red = (201, 4, 4)
  brown = (60, 50, 0)
  orange = (255, 150, 0)

  #pink
  light_pink = (245, 107, 255)
  dark_pink = (85, 1, 91)
  pink = (182, 25, 193)
  purple = (85, 1, 91)

  #yellow
  yellow = (225, 225, 0)

  #Less Common Colours

  turquoise = (0, 255, 178)
  white = (255, 255, 255)
  black = (0, 0, 0)

Thank you so much!!! I really appreciate it!
