Description:

ttystatus is a Python library for showing progress reporting and
status updates on terminals, for (Unix) command line programs. Output
is automatically adapted to the width of the terminal: truncated if it
does not fit, and re-sized if the terminal size changes.

Output is provided via widgets. Each widgets formats some data into a
suitable form for output. It gets the data either via its initializer,
or from key/value pairs maintained by the master object. The values
are set by the user. Every time a value is updated, widgets get
updated (although the terminal is only updated every so often to give
user time to actually read the output).
