Terminal application with non-standard print

[Rémi]

Hello everyone,

I would like to do a Python application that prints data to stdout, but
not the common way. I do not want the lines to be printed after each
other, but the old lines to be replaced with the new ones, like wget
does it for example (when downloading a file you can see the percentage
increasing on a same line).

I looked into the curses module, but this seems adapted only to do a
whole application, and the terminal history is not visible anymore when
the application starts.

Any ideas?

Thanks,

Remi
