为什么这个python理解多次重复用户输入？

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: "))

用户输入这样的列表：

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

然后，我尝试使用以下行来删除列表中的空格：

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

如果我之后打印列表理解，列表会一遍又一遍地重复：

基本上，您的列表理解是剥离整体sg_list_input，而不仅仅是一个元素sg。此外，用户输入将被解释为字符串，因此您需要将其拆分为一个列表。试试这个：
sg_list_input = [sg.strip(' ') for sg in sg_list_input.split(",")]





回答

您实际上是在遍历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，您应该首先用逗号分隔，然后按如下方式从列表的每个元素中去除空格，
sg_list_input = [sg.strip(' ') for sg in sg_list_input.split(',')]

继续编码！
