See python cookbook. The idea is simply to print out stuff and when updating,
erase previous characters eg. using '\r' ASCII code. Python Cookbook has a
progress bar implementation, you could use that as a basis for your code
(speed, t/elapsed and t/remaining are technically no different; if you can do
a progress bar, you can do those others as well).
