variable gets lost

Going back to your original post, in addition to what ichabod801 pointed out, lines 10 and 11 are not indented properly. Also, in line five you are iterating through the list 'admin' and can be simplified to

def login(name):
    if name in admin:
        print("Welcome in the system " + name)
        logged_in = 1
    else:
        print('you are not an admin')
