Regex to return only numbers
Hello!

I have a string like:
Code:
MyData 68309486 Bob


How can I use regex in python to return only 68309486? Only the numbers?

Python Code:
Original - Python Code 
  1. >>> import re
  2. >>> s = 'MyData 68309486 Bob'
  3. >>> patt = re.compile(r'[0-9]+')
  4. >>> patt.search(s).group(0)
  5. '68309486'
  6. >>>

You can also use \d as a shortcut for [0-9], so "\d+" will work just as well.

As I understand it, \s+ regex is the equivilent of saying "match 1 or more occurencies of any whitespace character" so the result it gives you; ' ' is correct


Edit: Ok you edited your previous post while I was responding, I'm not great with regexes but hopefully the above will answer the old question
