Help with conversion program - uwl - Aug-19-2022
I have errors in my code, it is for converting RGB to Hex in python.
def color(RGB):
if RGB > 255:
RGB = 255
elif RGB < 0:
RGB = 0
RGB = hex(RGB)[2:].upper()
if len(RGB)<2:
RGB = '0'+RGB
return RGB
def rgb(r, g, b):
return color(r)+color(g)+color(b)It shows for line 7. the following is thrown:Error:TypeError: object of type 'int' has no len()I already tried adding
str() to len(RGB)<2: with no successes.

Your indentation was wrong on line 6. This was only called if RGB < 0
RGB = hex(RGB)[2:].upper()Use f'string formatting. It will do the zero fill and upper case for you. In the code below, "02X" Says convert to upper case hexadecimal (X) and pad with 0 (0) to a width of 2 characters (2). I also prefer using min and max for clipping numbers to a range.
def rgb2hex(r, g, b, prefix=""):
clipped = (max(0, min(255, c)) for c in (r, g, b))
return prefix + "".join((f"{c:02X}" for c in clipped))
print(rgb2hex(184, 7, 280, "#"))Output:#B807FF
