can someone please he

Answer 1

I have some experiments about regex in django url, which required from negative to positive numbers

^(?P(\-\d+|\d+))$

Let's we focused on this (\-\d+|\d+) part and ignoring others, this semicolon | means OR in regex, then if we got negative value it will be matched with this \-\d+ part, and positive value into this \d+ part
