I use Cursor to convert it, but it may not work.
Converting Python code to B4A (Basic4android) code is not straightforward due to the differences in syntax, libraries, and overall language design. However, I can provide a rough equivalent of your Python code in B4A.
Please note that B4A doesn't have a direct equivalent for Python's CSV reader or dictionary. So, we'll use Lists and Maps instead. Also, B4A doesn't support command-line arguments, so we'll use hardcoded filenames for simplicity.
