Thanks everybody , and especially Chris - i used split and it took me 15

The final version looks like:

today_day = datetime.now()

Good day everyone,
I am trying to make this pretty simple regex to work but got stuck,
I'd appreciate your help .
Task: Get current date , then read file of format below, find the line that
matches
the current date of month,month and year and extract the number from such
line.
Here is what I did ,
Thanks,
works great.

Just curious, but since this is just transpose, then why not simply

This isn't a regex solution, but uses pyparsing instead. Pyparsing
