Python autocomplete user input

Question

I have a list of teamnames. Let's say they are

teamnames=["Blackpool","Blackburn","Arsenal"]

In the program I ask the user which team he would like to do stuff with. I want python to autocomplete the user's input if it matches a team and print it.

So if the user writes "Bla" and presses enter, the team Blackburn should automatically be printed in that space and used in the rest of the code. So for example;

Your choice: Bla (User writes "Bla" and presses enter)

What it should look like

Your Choice: Blackburn (The program finishes the rest of the word)

So what have you tried till now, you should include that too. Let us see your efforts till now. Where are you stuck exactly in your code. — , Jan 07 '14 at 14:02
Why is this question off topic? it seems to clearly ask for how to implement "enter"-completion (like tab-completion) in python given a list of possible inputs. — travelingbones, Jan 11 '17 at 20:44

teamnames=["Blackpool","Blackburn","Arsenal"]

user_input = raw_input("Your choice: ")

# You have to handle the case where 2 or more teams starts with the same string.
# For example the user input is 'B'. So you have to select between "Blackpool" and
# "Blackburn"
filtered_teams = filter(lambda x: x.startswith(user_input), teamnames)

if len(filtered_teams) > 1:
    # Deal with more that one team.
    print('There are more than one team starting with "{0}"'.format(user_input))
    print('Select the team from choices: ')
    for index, name in enumerate(filtered_teams):
        print("{0}: {1}".format(index, name))

    index = input("Enter choice number: ")
    # You might want to handle IndexError exception here.
    print('Selected team: {0}'.format(filtered_teams[index]))

else:
    # Only one team found, so print that team.
    print filtered_teams[0]

That depends on your usecase. If your program is commandline based, you can do that at least by using the readline module and pressing TAB. This link also provides some well explained examples on that since its Doug Hellmanns PyMOTW. If you are trying that via a GUI it depends on the API you are using. In that case you need to deliver some more details please.
