Python 自动完成用户输入

Question

我有一个团队名称列表。让我们说他们是

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

在程序中，我问用户他想和哪个团队一起做事。如果用户的输入与团队匹配并打印，我希望 python 自动完成用户的输入。

因此，如果用户输入“Bla”并按下enter，则 Blackburn 团队应自动打印在该空间中并在其余代码中使用。例如；

您的选择：Bla（用户输入“Bla”并按下enter）

它应该是什么样子

您的选择：布莱克本（该程序完成了单词的其余部分）

Answer 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]
