Greetings
There are many regex templates and one line. Seeking a reasonable way to determine which template matches a string.
At the moment, I'm running a string through the loop from the templates and checking if it matches the pattern.
import re patterns = [ (re.compile("^/upload/test/$"), "upload"), (re.compile("^/download/test/$"), "download"), (re.compile("^/test/$"), "test")] string = "/test/" for pattern in patterns: if pattern[0].match(string): print pattern[1] Is there a better way?
You have chosen quite suitable way. With a cursory reading of the dzhangovsokogo urlresolvera like it becomes clear that everything is the same as yours.
Not a big deal but it's
patterns = [ (re.compile("^/upload/test/$"), "upload"), ... ] can be changed to
patterns = ( (re.compile("^/upload/test/$"), "upload"), ... ) It seems that here it is proved that tuple (sorry, I don’t know how to translate) is faster than the list in initiation and iteration.
