How to extract info from a text column using regex in Python

Viewed 32

I have a dataset (csv file) of laptop reviews from users extracted from amazon. The columns are id, title, text, star, company and product. The column text has the detailed reviews from which I want to extract the laptop specifications like 8 GB, 250 GB, i5 or i7 processor, 14 inch screen, etc I tried using re.findall and str.findall, but got errors.

Appreciate if anyone could help me with this issue.
