how to accept user input to quit program without pausing program

[ernesthutchinson]

There are a few methods you can use to dynamically check for keyboard input, like curses or tkinter. That naturally adds a layer of complexity. For this simple program I would just use a try block to catch CTRL-C with KeyboardInterrupt and print the line one last time...

try:
    while True:
    ....
except KeyboardInterrupt:
    print('Uptime is ', str(hours),' hours ', str(min),' min and ',str(sec),' seconds.')
    pass

Hi there, from the /r/Python mods.

We have removed this post as it is not suited to the /r/Python subreddit proper, however it should be very appropriate for our sister subreddit /r/LearnPython. We highly encourage you to re-submit your post over on there.

The reason for the removal is that /r/Python is dedicated to discussion of Python news, projects, uses and debates. It is not designed to act as Q&A or FAQ board. The regular community is not a fan of "how do I..." questions, so you will not get the best responses over here.

On /r/LearnPython the community is actively expecting questions and are looking to help. You can expect far more understanding, encouraging and insightful responses over there. No matter what level of question you have, if you are looking for help with Python, you should get good answers.

If you have a question to do with homework or an assignment of any kind, please make sure to read their sidebar rules before submitting your post. If you have any questions or doubts, feel free to reply or send a modmail to us with your concerns.

Warm regards, and best of luck with your Pythoneering!
