def rgbToDecimal(rgbList):
    red = rgbList[0]
    green = rgbList[1]
    blue = rgbList[2]
    rgbInt = (red << 16) + (green << 8) + blue
    return rgbInt

a = rgbToDecimal([255, 0, 255])
print(a)

decimal转rgb:

def decimalToRgb(rgbInt):
    blue = rgbInt& 255
    green = (rgbInt>> 8) & 255
    red = (rgbInt>> 16) & 255
    return red, green, blue
    
b = decimalToRgb(16711935)
print(b)
