The question is: The Question is:
I have 2 csv files, one of them has only one "email" column with several lines of valid emails, I also have another file that has the same emails and some more, in this file there are other columns like, Country, City, Name etc..
My goal is to filter the second file all lines in which email is present the valid email file + invalid + info (country, city, etx..) Like this:
File of valid emails:
email |
------------------
[email protected]
------------------
Valid + invalid + email file:
email | name | city | country
------------------------------
[email protected] | Miguel | Porto | PT
------------------------------------------
[email protected] | Invalid | Lisbon | PT
The result should be all valid emails + info:
email | name | city | country
------------------------------
[email protected] | Miguel | Porto | PT
------------------------------------------
Files contain thousands of lines, not feasible to delete line by line. How can I do this? Thank you!
