[Tutor] Writing to the terminal?

[Karim]

I suppose we can do something like that (kind of pseudo code) to fully 
configure it:


def doSomeStuff(*args):
       ...

def progressBar( func, *args)
       import time, sys
       f = sys.stdout
       for i in range(20):
             func.__call__(args)
             f.write('=')
             f.flush()  # make the change visible immediately
       else:
             f.write('\n')

progressBar( doSomeStuff )

Cheers
Karim
