The output shows that the even number of backslash characters are included in the result string. In this article, you learned the basics of raw strings in Python. Continue your learning aboutPython strings.
In Short: Python Raw Strings Ignore Escape Character Sequences How Can Raw Strings Help You Specify File Paths on Windows? How Can Raw Strings Help You Write Regular Expressions? What Should You Watch Out for When Using Raw Strings? When Should You Choose Raw Bytes Over Raw String Literals?
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, ...
核心笔记 : Python 原始字符串(raw strings)的用法 你可能已经看到前面关于原始字符串用法的一些例子了。原始字符串的产生正是由于有正则表 达式的存在。原因是ASCII 字符和正则表达式特殊字符间所产生的冲突。比如,特殊符号“\b”在 ASCII 字符中代表退格键,但同时“\b”也是一个正则表达式的特殊符号,代表“匹配一...

本篇源自py2.7.9-docs的faq.pdf中的“3.23 Why can’t raw strings (r-strings) end with a backslash?” 更准确的说,原始字符串即以r修饰的字符串,不能以奇数个反斜杠结束; 原始字符串被设计用来作为一些处理器(主要是正则表达式引擎)的输入。这种处理器会认为这种未匹配的末端反斜杠是种错误,所以,原始字符...
Version 3.18.0 of Rouge included a new mechanism for handling strings in the Python lexer. One of the consequences of that change was that raw strings would break if they included 'invalid' escape sequences. This is a mistake as raw strings do not have 'invalid' escape sequences. This co...
