Display a countdown for the python sleep function


I am using time.sleep(10) in my program. Can display the countdown in the shell when I run my program?

>>>run_my_program()
tasks done, now sleeping for 10 seconds

and then I want it to do 10,9,8,7....

is this possible?


Solution

  • you could always do

    #do some stuff
    print 'tasks done, now sleeping for 10 seconds'
    for i in xrange(10,0,-1):
        time.sleep(1)
        print i
    

    This snippet has the slightly annoying feature that each number gets printed out on a newline. To avoid this, you can

    import sys
    import time
    for i in xrange(10,0,-1):
        sys.stdout.write(str(i)+' ')
        sys.stdout.flush()
        time.sleep(1)
