python - How to use regex to parse a number from HTML?

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

Your number is <b>123</b>

Now, how can I extract "123", i.e. the contents of the first bold text after the string "Your number is"?
