Python binding prints progress on multiple lines instead of updating in place

Hi, thank you for the great library!

I tried using the Python bindings for the progress indicator, but it doesn't behave as expected. Instead of updating the progress on a single line, it prints on multiple lines, which clutters the output.

I'm running this in a standard terminal (not a notebook), and I expected a single-line progress bar (similar to how tqdm works). It seems like carriage returns (\r) or output flushing might not be handled correctly in the Python binding.

Would it be possible to fix this or provide guidance on how to get a clean, single-line progress display?

Thanks again for your work!
