Question

I have a string coming from db, for example:

"any string coming from db[090876]"

I want to just fetch the numeric data and use it. In this case I just want 090876. How can I do it in Python/Django? I have tried with ‘re’ but no luck.

Answer 1

In [74]: import re

In [75]: re.findall('\d+',"any string coming from db[090876]")
Out[75]: ['090876']

or digits only between parens with db before it to be safe:

In [76]: re.findall('db\[(\d+)\]',"any string coming from db[090876]")
Out[76]: ['090876']
