How to write a regular expression in Python

Question

I want to write a simple regular expression in Python that extracts a number from HTML. The HTML sample is

Your number is <b>999</b>. So I want to extract only 999 from this. How to do it?

Answer 1

The following code should be able to do it. This will capture only 999 from the tag.

a = "Your number is <b>999</b>"
import re 
m = re.search(r"\d+", a)
m.group()
