如何拆分用户输入，使其在数组中占据两个索引位置？ (Python)

Question

我希望能够接受用户输入的几个用逗号分隔的不同单词，然后将它们添加到一个数组中，以便他们输入的每个单词都占用不同的索引值。这是我为此使用的功能：

array = ["cat","dog","house","car"]
print(array)

def append():#accepts a user input and adds it to the array
item = input("What would you like to append: ")
item = item.lower()
array.append(item)#appends the item variable delcared in the above statement
print ("The list is now: ",array)

目前，这是通过获取一个用户输入，将其更改为小写，将其添加到数组并打印出来来实现的。我想要它，以便用户可以输入：mouse、horse、mountain，程序会将这三个项目分别添加到数组中。目前它将它们全部加在一起——这是应该的。我已经尝试过 split() 命令，但是似乎所做的只是将它们作为一件事添加，然后将它们放在方括号中。

任何帮助都会很棒。干杯

Answer 1

你可以使用split func:

lst = string.split(", ")

它 returns 一个字符串列表。

输入：

Apple, Facebook, Amazon

lst:

["Apple", "Facebook", "Amazon"]

更新

获得列表后，您可以将它们添加到主列表（无论您如何称呼）：

array += lst

现在 array 包含这些：

["cat","dog","house","car","Apple", "Facebook", "Amazon"]

Answer 2

像这样

lst = ["cat","dog","house","car"]

def append():
  item = input("What would you like to append: ")
  lst.extend(item.lower().split(','))
 
print(f'Before: {lst}')
append()
print(f'After: {lst}')

Answer 3

You are thinking in the right direction, as one answer pointed out that you can use .split() method I will try to explain it a little more. You can create an item list to store the list of strings to be appended. Something like this

```python
item = input("What would you like to append: ")
item_list=item.split(", ")
```

Now you can use for loop to append this list your original array. Something like this..

```python
for item in item_list:
    item=item.lower()
    array.append(item)
```

Whole code for reference..

```python
array = ["cat","dog","house","car"]
print(array)

def append():#accepts a user input and adds it to the array
   item = input("What would you like to append: ")
   item_list=item.split(", ")
   for item in item_list:
       item = item.lower()
       array.append(item)     #appends the item variable
print ("The list is now: ",array)```
