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：

\dAny digit

+One or more of the previous expression (e.g., \d+ matches one or more digit)
[^/]+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
符号匹配
. (dot)任意字符
\d任意数字
[A-Z]任意字符, A-Z (大写)
