Problem Statement
On Windows, how should you open a CSV to avoid extra blank lines when writing?
Explanation
The csv module expects newline empty string to manage newlines correctly on Windows. Without it, you can get extra blank rows.
This setting lets the csv writer handle line endings consistently across platforms.
