simple usage example misleading

[thorstenkampe]

The simple usage example assumes that the total number of items to process is 5 and iterates over range(5 + 1) (= 6) items in order to draw a full 100%. Obviously you cannot iterate six times in a loop over a list of five items.

The following shows a "real life" usage example:

progress_set = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10)

total = len(progress_set)
bar   = ProgressBar(total)

for index, item in enumerate(progress_set):
    bar.numerator = index
    print(bar, end = '\r')

    # do stuff with item of progress_set
    time.sleep(0.25)

bar.numerator += 1
print(bar)

example.py shows in progress_bar() print(bar) # Always print one last time. This is probably an - incomplete - remainder of the correct usage. The author just forgot to increment the numerator.
