如何从用户输入中调出列表项

Question

我正在寻找一种用户输入变量的方法，它可以从列表中的特定位置调用列表信息

list = ["0","2","4","8"]

a = input("Enter the list entry you want to retrieve: ")

print (list[a])

如果输入1，则将打印2，如果输入2，则将打印4

Answer 1

将“ a”转换为整数。

list = ["0","2","4","8"]

a = input("Enter the list entry you want to retrieve: ")

print (list[int(a)])
