import random 
import string

random.choice(string.ascii_lowercase)

choice to select from 'abcdefghijklmnopqrstuvwxyz' exclude 'abd' from the choice generated by the random function

You can remove all a,b,d characters by replacing them with an empty string:

import re

s = re.sub('[abd]', '', string.ascii_lowercase)

Use this:

import random 
import string

unwanted_chars = 'abd'
random.choice([s for s in string.ascii_lowercase if s not in unwanted_chars])
