访问名称来自用户输入的局部变量 [英] Accessing a local variable whose name comes from user input

问题描述

我需要使用raw_input访问字符串.

i need to access strings using raw_input.

list1 = ["one","Two","three"]

list2 = ["1","2","3"]

while True:

        ip = raw_input("enter list: ")
        for i  in  ip:
                    print i
        break

当"list1"作为输入给出时，它作为字符串而不是列表. 我需要访问上面定义的列表. 我需要一种访问列表并打印列表的方法.

When "list1" is given as input, it takes as string but not as list. I need to access the list defined above. I need a way to access the lists and print the list.

推荐答案

使用字典:

lists = {
    "list1": ["one","Two","three"],
    "list2": ["1","2","3"],       
}

while True:
    choice = raw_input("enter the list name: ")
    try:
        for item in lists[choice]:
            print item
    except KeyError:
        print "I never heard of any list named '{}'! Try again.".format(choice)
    else:
        break
