Functions Practice

Doc2Doc should seamlessly convert hex triplet color codes to RGB values. Hex colors are an efficient means of representing color with only 6 characters. RGB values combine red, green and blue light to electronically display the entire color spectrum.

Assignment

Debug the hex_to_rgb function. hex_to_rgb should take a hex triplet color code and return three integers for the RGB values using int().

Some of the arguments passed to int() on lines 4, 5, and 6 are incorrect. Review the linked documentation to see how to convert hexadecimal (base 16) values.
Use the provided is_hexadecimal function inside of hex_to_rgb to check if hex_color is a valid hexadecimal string.
If the input is not six characters long or is not a valid hex string, raise the exception "not a hex color string".

Example:

red_val: int
green_val: int
blue_val: int
red_val, green_val, blue_val = hex_to_rgb("A020F0")

print(red_val)
# prints 160

print(green_val)
# prints 32

print(blue_val)
# prints 240
