我的 urls.py 中具有以下正则表达式(regex)，我想知道它的含义.特别是正则表达式的(?P< category_slug> 部分.

  r'^ category/(?P< category_slug> [-\ w] +)/$

(?P< name> regex)-圆括号将正则表达式分组.它们捕获其中正则表达式匹配的文本，这些文本可以用尖括号之间的名称引用.名称可以由字母和数字组成.

I have the following regular expression (regex) in my urls.py and I'd like to know what it means. Specifically the (?P<category_slug> portion of the regex.

r'^category/(?P<category_slug>[-\w]+)/$

解决方案

(?P<name>regex) - Round brackets group the regex between them. They capture the text matched by the regex inside them that can be referenced by the name between the sharp brackets. The name may consist of letters and digits.
