Python Autocomplete User Input

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 pytho

Solution 1:

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]

Solution 2:

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.
