We import the 're' module to access regex functionality. The pattern `r'(\d)+(?=x)'` is constructed. Here's the breakdown: `(\d)+` captures one or more digits as a group. `(?=x)` employs a positive lookahead assertion, ensuring the captured digits are followed by 'x'. The `...
Grouping also enables capturing. Using parentheses, you can capture and refer to the matched substring later. For example, consider the pattern: /(ab)+c/. In this pattern, the group (ab) is captured. If the string “ababc” matches this pattern, you can access the captured group and ret...

正则表达式(Regluar Expressions)又称规则表达式,在代码中常简写为REs,regexes或regexp(regex patterns)。它本质上是一个小巧的、高度专用的编程语言。通过正则表达式可以对指定的文本实现 匹配测试、内容查找、内容替换、字符串分割等功能。正则表达式的语法不是本节要讲的内容(关于正则表达式的详细介绍请参考另一篇博文...
