如何检查字符串是否是字符串列表中项目的子字符串? [英] How to check if a string is a substring of items in a list of strings?

问题描述

我有一个清单:

my_list = ['abc-123', 'def-456', 'ghi-789', 'abc-456']

并且想要搜索包含字符串 'abc' 的项目.我该怎么做?

and want to search for items that contain the string 'abc'. How can I do that?

if 'abc' in my_list:

将检查列表中是否存在 'abc' 但它是 'abc-123' 和 'abc-456' 的一部分>, 'abc' 本身不存在.那么如何获取包含 'abc' 的所有项目?

would check if 'abc' exists in the list but it is a part of 'abc-123' and 'abc-456', 'abc' does not exist on its own. So how can I get all items that contain 'abc'?

推荐答案

如果您只想检查列表中任何字符串中是否存在abc，您可以尝试

If you only want to check for the presence of abc in any string in the list, you could try

some_list = ['abc-123', 'def-456', 'ghi-789', 'abc-456']
if any("abc" in s for s in some_list):
    # whatever

如果你真的想得到所有包含abc的项目，使用

If you really want to get all the items containing abc, use

matching = [s for s in some_list if "abc" in s]
