Grab Yes/No after a particular word in Python

Question

I have a huge text document lets say of 1000's of words and with way too many lines in the text.

I want to grab specific value of a particular word. In my example word is Teetotlar and value is Yes or No

Sample text:

I am going to a party with my friends. I have lot of friends. they are all coming to party. I will be happy to see each of them.

Many of my friends drink but if you ask them r you teetotlar, they would probably reply yes.

But it is all good.

I have working code for:

Read all lines one by one
Check for teetotlar word
Again check if that have "Yes" or "No" and then save that value in one variable

What I want:

Is to have a regex which just checks for the word Teetotlar in the whole text and then looks for value Yes or No in the same line.

`\bTeetotlar\b.*\b(Yes|No)\b` ([regex101](https://regex101.com/r/Whv0PI/1)) — Aaron, Dec 21 '18 at 10:08

Here is one approach:

line = "Many of my friends drink but if you ask them r you teetotlar, they would probably reply yes."

m = re.search( r'\bteetotlar\b.*\b(?:yes|no)\b', line, re.M|re.I|re.DOTALL)
if m:
    print "the line matches"

This would let you check the line for teetotler and yes/no, with the former occurring before the latter.

Instead of line, can I pass my whole text ? – Rahul Agarwal Dec 21 '18 at 10:17
You would need to give us more information. Do you expect a report of which lines matched and which did not? Or, do you want a single scan of all lines, with a report of whether one single line matched? – Tim Biegeleisen Dec 21 '18 at 10:18
I want to grab Yes or No after teetotlar..that's it. Irrespective of which line, which paragraph it is coming – Rahul Agarwal Dec 21 '18 at 10:20
@RahulAgarwal Use DOTALL mode and my updated answer should work. – Tim Biegeleisen Dec 21 '18 at 10:24
Only after teetotalar, I want to capture "Yes/No" not before that!! So yes order matters – Rahul Agarwal Dec 21 '18 at 10:25

On doing `print m.groups()` it isn't returning me anything – Rahul Agarwal Dec 21 '18 at 10:33
Just need to do `re.findall` instead of `re.match`. Thanks for your help and patience!! – Rahul Agarwal Dec 21 '18 at 10:38
