In this unit, you use the most common string methods in Python to manipulate strings, from simple transformations to more advanced search-and-replace operations.
一个Regex对象的search()方法在传递给它的字符串中搜索正则表达式的匹配项。如果在字符串中没有找到正则表达式模式,search()方法将返回None。如果发现模式,则search()方法返回一个Match对象,该对象有一个group()方法,将从搜索的字符串中返回实际匹配的文本。(我很快会解释组。)例如,在交互式 Shell 中输入以下内容:...
