与字符串中模式有关的正则表达式时,我们会用术语 “matching”(“匹配”),指的是术语pattern-matching(模式匹配)。在Python专门术语中,有两种主要方法完成模式匹配:搜索(searching)和匹配(matching)。搜索,即在字符串任意部分中查找匹配的模式,而匹配是指,判断一个字符串能否从起始处全部或部分的匹配某个模式。搜索通...
在Python中,有两种主要方法完成模式匹配:搜索(searching)和匹配(matching)。搜索是在字符串任意部分中查找匹配的模式;而匹配是指判断一个字符串能否从起始处全部或部分的匹配某个模式。搜索通过search()函数或方法来实现,而匹配是match()函数或方法实现的。

Before we extract the matching string, let’s look at the RegEx pattern. regex_pattren = pre.get_pattern() print(regex_pattren) Output As we can see, it is hard to read or even understand what is going on. This is where PRegEx shines. To provide you with a human-friendly API for ...
