首先,我们需要定义一个工具函数,该函数接收一个字符串作为输入,并返回一个转义后的正则表达式字符串。 importredefconvert_to_regex(pattern):regex=re.escape(pattern)returnregex 1. 2. 3. 4. 5. 使用示例 接下来,我们将演示如何使用上述工具函数将字符串转换为正则表达式。 pattern="(Hello)"regex=convert_to...
If you’re not using a raw string to express the pattern, remember that Python also uses the backslash as an escape sequence in string literals; if the escape sequence isn’t recognized by Python’s parser, the backslash and subsequent character are included in the resulting string. However, ...
I use the following method to convert a python string (str or unicode) into a raw string: def raw_string(s): if isinstance(s, str): s = s.encode('string-escape') elif isinstance(s, unicode): s = s.encode('unicode-escape') return s Example usage: import res = "This \\"re.su...

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 ...
