[SOLVED] Choose specific user from list using `os.system()`

Issue

I need to create a menu screen in Python of all the users in the system, and after the system displays the list you choose the user you want and then another menu should pop-up.

So far I have:

os.system("cut -d: -f1 /etc/passwd")    
chose = str(raw_input("Select user from this list > "))

How can I make the second list appear after I choose a user?

Solution

You can use pwd and grp modules.
We use grp to get user group.

import pwd, grp

user = ''
users = pwd.getpwall()
i=0
for p in users:
    print str(i) + ')' + str(p[0])
    i+=1


chose = int(raw_input("Select user from this list > "))
user = users[chose]
print
print '1) show user groups \n2) show user id'
print 
chose = int(raw_input("Your choice > "))

if chose == 1:
    print grp.getgrgid(user.pw_gid).gr_name
else:
    print user.pw_uid
