Let's take a look at the Chapter17/example1.py file, as follows:
# Chapter17/example1.pyimport timedef count_down(name, delay): indents = (ord(name) - ord('A')) * '\t' n = 3 while n: time.sleep(delay) duration = time.perf_counter() - start print('-' * 40) print('%.4f \t%s%s = %i' % (duration, indents, name, n)) n -= 1start = time.perf_counter()count_down('A', 1)count_down('B', 0.8)count_down('C', 0.5)print('-' * 40)print('Done.')
The goal of this example is to illustrate the asynchronous nature of overlapping the processing and waiting time of independent tasks. To do this, we will be analyzing a countdown function (count_down()) that takes in a string and a delay time. It will then count down from three to one, ...
