Hi, I'm new to the forum and have a question about looping through rows to check for values at specific columns.

I have a csv file with 20 some columns and hundreds of rows. Basically, what I want to do is delete all the rows where column 12 is 1 or column 15 is a 1. I've seen many examples of how to delete some arbitrary row or search for some arbitrary string but nothing about checking for a string at a specific spot (like "1" in column 12) and then deleting that row. What I'd really like to know is how to reference a specific column - something like "elementAt(12)" - so I can create conditionals.

Any help would be appreciated.

Also, I'd like this to be done in a new CSV file. Thanks!
