http://wiki.c2.com/?RawStrings | |
Raw string 是个通用概念。即 escape 不生效的 string,既然不生效,也无法 escape 掉 ending sequence。 | |
所有语言的 raw string 都面临一个问题,即如何处理 ending sequence | |
Python | |
https://docs.python.org/3/reference/lexical_analysis.html#string-and-bytes-literals | |
staring sequence: “ or ' | |
ending sequence: “ or ' | |
Python 的做法是允许 ‘, “ 出现,但需要用 \ escape 掉它们(相当于在 Python raw string里有唯一生效的escape就是\”和\’),并且 \ 依然会出现 |
