How do I read a command line argument from Python?

I am new to python programming, but basically I want to have a script where when given a file path from the command line (the file being a .csv file), the script will take this file and turn it into a list.

Code I have seen for this problem usually doesn't take the file from the command line, rather it just has the exact filename in the code. I want to use this code on many different files, so hard coding the file name into the program is not an option.

The only change you need to make to the code that you've already found is this:

import sys
filepath = sys.argv[1]
... # process file

And now, you invoke your script like this: ./script.py /path/to/file.

sys.argv is used to read command line arguments. Optional commands start from index 1, because argv[0] stores the name of your script (script.py).
