从一个列表中输入要添加到另一个列表的元素

Question

我的 python 旅程还很早，所以我的编码知识非常基础。简单的答案表示赞赏。

我这里的挑战是创建一个函数来 select 列表中的一个项目添加到另一个列表

这里是大致思路的伪代码：

# My Lists
list1 = ["item1", "item2", "item3", "item4", "item5"]
list2 = []

# print verticle, indexed list
for element in (list1):
            print(list1.index(element) + 1, element)

# create function to input selected item an add to list2
def selectitem():
     selection = input("Enter the number of item you'd like to add to list2: ")
     if selection == "1": # How would I now define "1" to select and append index 0 from list1 to list2?
          list2.append(selection)

我希望你已经清楚了。总之，如果我在输入中输入“1”，我想将索引 0 添加到 list2。任何关于如何做到这一点的简明解决方案将不胜感激！

Answer 1

#My Lists
list1 = ["item1", "item2", "item3", "item4", "item5"]

list2 = []

#create function to input selected item an add to list2

def selectitem():

    selection = int(input("Enter the number of item you'd like to add to list2: "))

    list2.append(list1[selection-1])

    print(list2)

selectitem()

从一个列表中输入要添加到另一个列表的元素

Input element from one list to add to another

python

indexing

list

append
