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)
