Use Regex re.sub to remove everything before and including a specified word

Question

I\'ve got a string, which looks like \"Blah blah blah, Updated: Aug. 23, 2012\", from which I want to use Regex to extract just the date Aug. 23, 2012. I found

Answer 1

You can use Lookahead:

import re
date_div = "Blah blah blah, Updated: Aug. 23, 2012"
extracted_date = re.sub('^(.*)(?=Updated)',"", date_div)
print extracted_date

OUTPUT

Updated: Aug. 23, 2012

EDIT
If MattDMo's comment below is correct and you want to remove the "Update: " as well you can do:

extracted_date = re.sub('^(.*Updated: )',"", date_div)
