I'e got a module 'cs.upd' on PyPI which does this. "pip install cs.upd" 
to obtain it.

Typical usage:

  import sys
  import time
  from cs.upd import Upd

  upd = Upd(sys.stdout)
  for percentage in range(1,100):
    upd.out("Progress: %d%%", percentage)
    if percentage % 10 == 0:
      upd.nl("completed %d%%", percentage)
    time.sleep(0.1)
  upd.out("Complete!")
  time.sleep(1.0)

That example is obviously contrived, and the sleeps are so you can see 
it all happen.  But you can slot this into simple terminal based 
programmes to present dynamic progress.
