Converting Hex to RGB value in Python

Question

Working off Jeremy's response here: Converting hex color to RGB and vice-versa I was able to get a python program to convert preset colour hex codes (example #B4FBB8), however from an end-user perspective we can't ask people to edit code & run from there. How can one prompt the user to enter a hex value and then have it spit out a RGB value from there?

Here's the code I have thus far:

def hex_to_rgb(value):     value = value.lstrip('#')     lv = len(value)     return tuple(int(value[i:i + lv // 3], 16) for i in range(0, lv, lv // 3))   def rgb_to_hex(rgb):     return '#%02x%02x%02x' % rgb  hex_to_rgb("#ffffff")              # ==> (255, 255, 255) hex_to_rgb("#ffffffffffff")        # ==> (65535, 65535, 65535) rgb_to_hex((255, 255, 255))        # ==> '#ffffff' rgb_to_hex((65535, 65535, 65535))  # ==> '#ffffffffffff'  print('Please enter your colour hex')  hex == input("")  print('Calculating...') print(hex_to_rgb(hex())) 

Using the line print(hex_to_rgb('#B4FBB8')) I'm able to get it to spit out the correct RGB value which is (180, 251, 184)

It's probably super simple - I'm still pretty rough with Python.

Answer 1

I believe that this does what you are looking for:

h = input('Enter hex: ').lstrip('#') print('RGB =', tuple(int(h[i:i+2], 16) for i in (0, 2, 4))) 

(The above was written for Python 3)

Sample run:

Enter hex: #B4FBB8 RGB = (180, 251, 184) 

Writing to a file

To write to a file with handle fhandle while preserving the formatting:

fhandle.write('RGB = {}'.format( tuple(int(h[i:i+2], 16) for i in (0, 2, 4)) )) 

Answer 2

You can use ImageColor from Pillow.

>>> from PIL import ImageColor >>> ImageColor.getcolor("#23a9dd", "RGB") (35, 169, 221)
