I have a csv file I have to make some changes to before I read it into
pandas. Currently I open the csv read each row, make changes and save it to
a new file. Then read it into pandas with pandas.read_csv(). How do I skip
writing the file to disk? Using python3.5.
This is what I am doing now.

Hi everyone,

purpose, and I think I've come to the right place :).
The construct is this:

Welcome to Python.

If you are on Microsoft Windows, choose the Start button, then type "cmd"
