### Create dynamically updatable progress bar

Hi!

Sometimes calculations takes a long time, and it'll be very useful to know the progress. A simple example:

from time import sleep

def slow_calculations():
for i in range(10):
sleep(0.5)
print 'Complete',(i+1)*10,'%'
print 'Done'


Such indication of process was my first solution. Is is possible somehow to draw a progress bar and update it's value during the calculations? Something like that:

def slow_calculations(bar):
for i in range(10):
sleep(0.5)
bar.value = (i+1)*10

progressBar= ProgressBar()
progressBar.show()
slow_calculations(progressBar)
