Random HTML CSS Hex Color Picker

BustACode 2 Tallied Votes 510 Views Share

I needed a random color selector. I found one here. I rewrote it to make it more general purpose.
"f_GenRandomColor" is the picker. The output is in list form, which should make it suitable for most general applications.
"f_HTMLRandomColorChart" is just a way to create an HTML table to test the output from.

Thanks to the original author.

Good effort,i give you a up vote:)
But have to mention your code style again,it's not so pretty.
I link to PEP-8 in your post,
just to show a doc that can help you in the future regarding code style.

Here a version i made,
Look a little at how code is formatet,
and names i use in code(No capitale letters,because that is used in class name).

#Testet work in Python 2 and 3
from __future__ import print_function
from random import randint
#Fix so input() work 2 and 3
try:
    input = raw_input
except NameError:
    pass

def random_hex_colors():
    return "#{:06x}".format(randint(0,0xFFFFFF)).upper()

def gen_html_tag(random_hex_colors, number_of_tags, width, filler_text):
    return \
    '\n'.join('<tr><td>{0}</td><td style ='
     '"background-color: {0};width:{1}px">{2}</td></tr>'
    .format(random_hex_colors(), html_width, text_filler)
    for i in range(number_of_tags))

def write_html(tag_gen, file_name):
    with open('{}.html'.format(file_name), 'w') as f_obj:
        f_obj.write('''\
<!DOCTYPE html>
<head>
<title>Random Color Chart</title>
</head>
<table border = "1">
<tr><th>Color Name</th><th>Color</th></tr>
{}
</table>'''.format(tag_gen))

if __name__ == '__main__':
    #Test without user input
    number_of_tags = 3
    html_width = 300
    text_filler = 'test'
    file_name = 'color_test'        
    #Call functions
    tag_gen = gen_html_tag(random_hex_colors,
    number_of_tags, html_width, text_filler)
    write_html(tag_gen, file_name)
