How to check url format through regex?

Question

My url is in the format of

/en/33/details

But the number 33 is dynamic and I have to check if the url has /en/ part and /details part and some number in between.

I tried checking through

if url == r'^/en/(?d[0-9]+)/details':

But i checked through the django url regex syntax but it doesn't work. May I know where I am going wrong

There is no (?d)-like regex construct in Python.

You need to use r'/en/\d+/details' with re.match.

if re.match(r'/en/\d+/details')

The re.match method anchors the search at the start of the string, so this will only find a match if

If you need to also anchor the pattern at the end, append $:

if re.match(r'/en/\d+/details$')  
                             ^
