How to extract the first float from a string in python

I have a string containing a string and word, I want to extract the first float the string.

myString = 12.5% per month
myFloat= [float(s) for s in re.findall(r'\b\d+\b', myString )][0]

I want to have 12.5 as myFloat.

Thank you

>Solution :

To not change your code completly:

import re
myString = "12.5% 35.6 per month"

myFloat= [float(s) for s in re.findall(r'[0-9]+.[0-9]+', myString )][0]

All I’ve changed is the regex expression to r'[0-9]+.[0-9]+'.
