You can. Assigning random usernames isn't usually considered a very
nice thing to do to users, but assuming you have a valid use-case
for it, it's just simple Python:
import random
import string
def random_username(characters=string.ascii_lowercase, length=10):
return ''.join(
random.choice(characters)
for _ in range(length)
)
You might also want to post-process to check for profanity in it, as
you you don't (usually) want to assign profanity as a username:
BAD_WORDS = [ ... ] # all in uppercase
while True:
username = random_username()
normalized_username = random_username.upper()
for word in BAD_WORDS:
if word in normalized_username:
break
else: # note this is at the indentation level of the "for", not "if"
break
print "Username:", username
It's not a perfect check, but it will eliminate the obviously
problematic ones based on your black-list
