Python String to triplet color

Question

Hov can I make a string triplet to a RGB color? Like this:

color = "255,255,255"
background.fill((color))

This code gives me "invalid color argument". Why I want to do it this way? This string is saved in a file.

Answer 1

pygame.Surface.fill expects:

The color argument can be either a RGB sequence, a RGBA sequence or a mapped color index. If using RGBA, the Alpha (A part of RGBA) is ignored unless the surface uses per pixel alpha (Surface has the SRCALPHA flag).

You could try something like

def str2rgb(s):
    rgba = s.split(",")
    if len(rgba) not in (3, 4):
        return (0, 0, 0)
    return tuple(map(int, rgba))


>>> color = "255,255,255"
>>> str2rgb(color)
(255, 255, 255)
>>> color2 = "255,255,255,0"
>>> str2rgb(color2)
(255, 255, 255, 0)
