如何在Python的用户定义搜索字符串中支持通配符? [英] How can I support wildcards in user-defined search strings in Python?

问题描述

在搜索字符串时是否有一种简单的方法来支持通配符("*")，而无需使用RegEx?

Is there a simple way to support wildcards ("*") when searching strings - without using RegEx?

用户应该使用通配符输入搜索词，但不必处理RegEx的复杂性:

Users are supposed to enter search terms using wildcards, but should not have to deal with the complexity of RegEx:

"foo*"   =>  str.startswith("foo")
"*foo"   =>  str.endswith("foo")
"*foo*"  =>  "foo" in str

(但是，当有多个搜索字词时，例如"foo bar baz"，它将变得更加复杂)

(it gets more complicated when there are multiple search terms though, e.g. "foobarbaz")

这似乎是一个常见问题，所以我想知道是否有现成的解决方案.

This seems like a common issue, so I wonder whether there's a ready-made solution for it.

任何帮助将不胜感激！

推荐答案

您可以尝试 fnmatch 模块，它具有类似shell的通配符语法.

You could try the fnmatch module, it's got a shell-like wildcard syntax.
