This is a python version from node-x256

Return the nearest xterm 256 color code for rgb inputs.

You can just print the index:

>>> from x256 import x256
>>> ix = x256.from_rgb(220, 40, 150)
>>> print ix

or you can use raw ansi escape codes:

from x256 import x256
ix = x256.from_rgb(220, 40, 150)
print '\x1b[38;5;' + str(ix) + 'mBEEEEEP'

output:
