为什么这个python理解会多次重复用户输入？

我要求用户使用python输入安全组列表：

sg_list_input = str(input("Enter a comma separated list of security groups to add: "))

用户输入如下列表：

sg-031ac185d029cd5fd, sg-05ef09508245e56bc, sg-0e4b5fc1d40185fc3, sg-2cad407c, sg-0afa867f9029bb468, sg-0333d9eaaeb3ab1b0, sg-0d0ddf3117d23cadb

然后，我尝试使用以下行提示列表中的空格：

sg_list_input = [sg_list_input.strip(' ') for sg in sg_list_input]

如果我随后打印列表，则列表会一次又一次地重复：

为什么会发生这种情况？我该如何更正它？

您显然没有拆分输入列表，因此它为输入中的每个字符添加了

sg\u list\u input.strip（“”）

，而不是每个逗号分隔的项，因此列表中出现了如此多的副本

另外，

strip（“”）

不会删除所有空格，只删除尾随空格和前导空格

如果要从

sg\u列表\u输入中删除所有空格，可以执行
replace（）
：

然后，如果希望每个项目都在列表中，可以使用
split（）
：

或者，正如其他人指出的，您可以使用列表理解在一行中完成所有操作

至于为什么我不只是在
，“
：用户可以使用空格，也可以不使用空格，这样它就可以处理这两种情况，输入是
“a，b，c，d”
或
“a，b，c，d”
。如果您在
，“
上拆分，则它不会在所有情况下都有效。输入提示显示输入一个逗号分隔的列表，用户可能会有不同的解释。大多数人自然都想添加空格，但那些按字面意思理解的人，可能使用过CSV文件，可能更倾向于不添加空格。

基本上，你对列表的理解是剥离整个
sg\u列表输入
，而不仅仅是一个元素
sg
。此外，用户输入将被解释为字符串，因此需要将其拆分为一个列表。请尝试以下方法：

sg_list_input = [sg.strip(' ') for sg in sg_list_input.split(",")]

sg_list_input = [sg.strip(' ') for sg in sg_list_input.split(",")]

实际上，您正在迭代从输入中获得的字符串对象，因此对于字符串上的每个字符，您都将整个字符串添加到列表中

相反，您应该先用逗号分隔，然后按如下所示从列表的每个元素中去除空白

sg_list_input = [sg.strip(' ') for sg in sg_list_input.split(',')]

继续编码

 仅供参考，我认为这里不需要列表理解

new_str = sg_list_input.replace(' ', '')
print(new_str.split(','))

很确定这就完成了你想要的

你在理解中使用了错误的变量。旁注，
str（input（））
是多余的，因为
input（）
返回一个
str
sg\u list\u input
不是
列表，而是
str
。因此，sg_列表中sg的
输入将在
str
中的每个字母上循环。您在理解中使用了错误的变量。旁注，

sg_列表中的输入

。正因为如此，
for sg in sg_list_input
将在

中的每个字母上循环。我将您的答案编辑为逗号分隔，因为没有这样做，您的答案是错误的。我以为用户正试图将字符串转换为列表并去掉空白？split（）将在任何空格上拆分如果未指定，则在逗号上拆分将保留空格。但是您先用
replace（“”，“”，“”，“”，“”，“”，“”，“”，“/code>split（）将不会拆分任何内容。如果您通过
replace（'，'，''）
删除了逗号，那么它就可以工作了。意识到您的权利，感谢hahaI将您的答案编辑为逗号分隔，因为如果不这样做，您的答案是不正确的。我以为用户试图将字符串转换为列表并去掉空白？split（）将在任何空格上拆分如果未指定，则在逗号上拆分将保留空格。但是您先用
