Here are some free Python file viewer and Python file editor software to help you open PY files on Windows 11/10 PC.

Remember that a CSV file is actually just a text document with a fancy formatting. That means that you actually don’t need to use a module if you want to know how to open CSV files in Python!

By using the open () function and a simple loop, you can cycle through a list of file names and assign a variable with a reference to that file, storing it for later use.
