string 对象的 split() 方法只适应于非常简单的字符串分割情形,它并不允许有多个分隔符或者是分隔符周围不确定的空格。当你需要更加灵活的切割字符串的时候,最好使用re.split()方法: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 >>>line='asdf fjdk; afed, fjek,asdf, foo'>>>importre>>>re.spli...
In this tutorial, you'll learn how to remove or replace a string or substring. You'll go from the basic string method .replace() all the way up to a multi-layer regex pattern using the sub() function from Python's re module.
re.escape(pattern) 转义pattern 中的特殊字符。如果你想对任意可能包含正则表达式元字符的文本字符串进行匹配,它就是有用的。比如 >>> 代码语言:javascript 代码运行次数:0 运行 AI代码解释 >>> print(re.escape('http://www.python.org')) http://www\.python\.org >>> legal_chars = string.ascii...
以下是正则表达式格式的简要说明。更详细的信息和演示,参考正则表达式HOWTO。 正则表达式可以包含普通或者特殊字符。绝大部分普通字符,比如'A','a', 或者'0',都是最简单的正则表达式。它们就匹配自身。你可以拼接普通字符,所以last匹配字符串'last'. (在这一节的其他部分,我们将用thisspecialstyle这种方式表示正则表...
