Time passes so fast - I would prefer to use f-strings, but I didn't realise that they were universally available yet. They're still a "new thing" as far as I'm concerned. I would prefer f-strings, I just used the str.format() method as a middle-ground. > So: > sys.stdout.write(f'\r{file_path} --> {rel_path} ({size/1024/1024} MB)\n') By the way, I have a patch coming soon that can print the size in human readable units: b, kb, Mb, Gb etc. rather than always converting it to Mb.
