It is better to just post the text in your question rather than posting *pictures* of text. Can you be more specific about what you want to extract? The value in `disply[2]` has more than a single number in iit. Do you just want a list of numbers? Do you need to preserve the tags? **Update your question** to show what you want the final values to look like. — larsks, Oct 27 '17 at 11:15

you can use re module in python

import re 
re.findall(r'\d+',display[2])
re.findall(r'\d+',display[3])

That would extract all the numeric values.
