Python3 Regex for extract digits

Question

I try to extract digits from urls with Python.

import re

url = '/randomtext/02@randomtext/01@randomtext/03@randomtext/01@.mp4'
for m in re.finditer(r'\d{2}', url):
    print(m[0], end='')

print function do this but I need the same result in variable, how can I did this?

Answer 1

s = "".join(m[0] for m in re.finditer(...))

Answer 2

Just use re.sub with an empty string as the replacement. That pattern should be fine.

url = '/randomtext/02@randomtext/01@randomtext/03@randomtext/01@.mp4'
print(re.sub(r'\d{2}', '', url))

Prints:

/randomtext/@randomtext/@randomtext/@randomtext/@.mp4
