Sure, you just need to print messages then the progress bar, without 
printing newline, then
sys.stdout.flush(), then in the next loop start by printing '\r' to 
erase the progress bar.

That is, if you want messages to scroll up. You can also use half a line 
for the progress
bar and the other half for a short message, then you print both with 
and erase both with '\r'.
