[Tutor] timer module question (original) (raw)

Today I've been studying the time module using the Python Library Reference. As an exercise I thought I'd make a timer script.

What I'd like to get it to do in addition, is tell me every 10 seconds how many seconds have elapsed while the timer is running. Is there a way to do this?

Here's what I have. It seems to work well:

===================================== #timer.py

import time

while True: start = raw_input("Press Enter to start timer; enter 0 to close program " t0 = time.time()

 if start == "0":
     print "Timer has been shut down"
     break

 time_now = time.ctime()
 print "Timer has been started at", time_now[11:19], "\n"

 raw_input("Press Enter to stop timer ")
 t1 = time.time()
 elapsed_time = t1 - t0
 time_now = time.ctime()
 print "\nTimer has been stopped at", time_now[11:19]
 print "Time elapsed was", elapsed_time, "seconds"
 print "-------------------------------------\n"

======================================

sample output:

Press Enter to start timer; enter 0 to close program Timer has been started at 16:37:48

Press Enter to stop timer

Timer has been stopped at 16:40:56 Time elapsed was 188.156000137 seconds

Press Enter to start timer; enter 0 to close program

(Later I'll want to trim the accuracy of the result, and also convert to hours, minutes, seconds, but I think I'll be able to figure that out. Being able to turn this into a GUI timer is way down the road for me.)

If it matters, I'm running Python 2.3.4 on Windows XP Pro

Thanks,

Dick Moores
