Regex capture group extracting elements of a list in a sentence

I have a list of sentences, with some that contain elements in sentence list form:

I only wish to extract elements from sentences that start with "You can get" or "You can get the" which I hope to extract using pandas extractall method, where I extract each individual element of the list in the sentences.

Desired output:

I have three main questions:

1. How to use look behinds (?<=[Y|y]ou can get ) so it won’t capture the
2. How to include the look ahead \w+(?=s)? so that both plural and singular forms of the elements are captured
3. Is it possible to write a capture group that also extracts each word as individual elements, or should I extract the list in the sentence first (e.g cars, trucks, planes, and boats) then run another regex?

>Solution :

What about using:

df.loc[df['sentence'].str.startswith('You can get '),
       'sentence'].str.extractall(r'(?P<object>\S+?)s?\b(?:,|.$)')

Output:

        object
  match       
0 0        car
  1      truck
  2      plane
  3       boat
1 0        car
  1      truck
  2      plane
