I am the author of Twython. Two different methods can be used for this; one that returns only identifiers get_followers_ids( get_followers_ids), and one that returns the status / etc of set get_followers_list( get_followers_list).
A sample code for one will look like this:
from twython import Twython
twitter = Twython()
followers = twitter.get_followers_ids(screen_name = "ryanmcgrath")
for follower_id in followers:
print "User with ID %d is following ryanmcgrath" % follower_id
, , (get_followers_list) , . , Twython API API Twitter, , , , .
