Generating a Random Hex Color in Python

Question

For a Django App, each \"member\" is assigned a color to help identify them. Their color is stored in the database and then printed/copied into the HTML when it is needed. T

Answer 1

Would like to improve upon this solution as I found that it could generate color codes that have less than 6 characters. I also wanted to generate a function that would create a list that can be used else where such as for clustering in matplotlib.

import random

def get_random_hex:
    random_number = random.randint(0,16777215)

    # convert to hexadecimal
    hex_number = str(hex(random_number))

    # remove 0x and prepend '#'
    return'#'+ hex_number[2:]

My proposal is :

import numpy as np 

def color_generator (no_colors):
    colors = []
    while len(colors) < no_colors:
        random_number = np.random.randint(0,16777215)
        hex_number = format(random_number, 'x')
        if len(hex_number) == 6: 
            hex_number = '#'+ hex_number
            colors.append (hex_number)
    return colors
