Python - Locating the position of a regex match in a string?

Question

I\'m currently using regular expressions to search through RSS feeds to find if certain words and phrases are mentioned, and would then like to extract the text on either si

Answer 1

You could use .find("is"), it would return position of "is" in the string

or use .start() from re

>>> re.search("is", String).start()
2

Actually its match "is" from "This"

If you need to match per word, you should use \b before and after "is", \b is the word boundary.

>>> re.search(r"\bis\b", String).start()
