Django正则表达式

正则表达式

Regular expressions (or regexes ) are a compact way of specifying patterns in text. While Django URLconfs allow arbitrary regexes for powerful URL-matching capability, youll probably use only a few regex patterns in practice. Heres a small selection of common patterns:

正则表达式 (或 regexes ) 是通用的文本模式匹配的方法。Django URLconfs 允许你 使用任意的正则表达式来做强有力的URL映射，不过通常你实际上可能只需要使用很少的一 部分功能。下面就是一些常用通用模式：

[^/]+	All characters except forward slash
?	Zero or more of the previous expression (e.g., \d* matches zero or more digits)
{1,3}	Between one and three (inclusive) of the previous expression
