The app lets you choose from multiple preset options, including keeping it awake for 5, 10, 15, or 30 minutes. It’s a suitable replacement for the now-defunct Caffeine. That would remind you to undo the hack after your presentation is over. KeepingYouAwake is a menu bar app based on the caffeinate command-line tool, designed to prevent your desktop Mac or MacBook from sleeping. The easiest thing to do would be to leave the Terminal open during your presentation. You need to remember that you’ve invoked it. I give presentations on my Macbook Pro all the time and I’m constantly swiping the trackpad to prevent the machine from going to sleep (even when I don’t have to). This command is appropriately called caffeinate. Instead, there’s a built-in terminal command that can temporarily keep your Mac awake and prevent all sleep settings. But this isn’t ideal, as it both involves a few extra steps and you may forget to set it back when you’re done. In these instances, you could go to System Preferences > Energy Saver and use the slider to tell your Mac to “never” sleep. Holding the alt key, the new window will be opened in the current frontmost Finder. But sometimes we intentionally don’t want our Macs to sleep, such as when preparing to give a Keynote presentation or when you’re letting a colleague or family member use your Mac. Alfred workflow to open a new Terminal/iTerm window in the current space. It can take a while.We generally want our Macs to sleep when not in use: saving battery life, reducing energy usage, and increasing the longevity of our Mac’s components. Hopefully this helps others who might be starting out and still haven't figured out how the computer thinks yet. In this next example, I use double quotes and it won't work because it thinks there is a break in the quotes between "the" and "function" even though when you read it, your own mind can make perfect sense of it: print("You have reached the end and the "input()" function is keeping the window open") "raw_input()", it will think it is a function, variable, etc, and not text. (2) Use single quotes to indicate a string otherwise if you type doubles around anything, such as (1) In python 3, there is no raw_input(), just This next example would give you a clear message that the program is done and not waiting on another input prompt within the program: print('You have reached the end and the "raw_input()" function is keeping the window open') This would just show a cursor with no text: raw_input() To just keep the window open I agree with Anurag and this is what I did to keep my windows open for short little calculation type programs. To keep the window open in any case: if _name_ = '_main_':įor Python3 you'll have to use input() in place of raw_input(), and of course adapt the print statements. To keep your window open in case of exception (yet, while printing the exception) Python 2 if _name_ = '_main_': That drops you to a python shell after the end of the program, with the program environment loaded, so you may further play with the variables and call functions and methods. I find it particularly useful to configure it as " python -i myscript.py" when running. Other editors allow you to configure the command line it uses to run your program. Some editors prepared for python will automatically pause for you after execution. Specially annoying when testing other people's scripts. That method is annoying because you have to modify the script, and have to remember removing it when you're done. at the end of the script makes it wait for the Enter key. When the program ends, it'll drop you back to the cmd prompt instead of closing the window.Īdd code to wait at the end of your script. Just check on how to edit environment variables on Windows, and add C:\PYTHON26 (or whatever directory you installed python to). Open a command prompt and type: python myscript.pyįor that to work you need the python executable in your path. Run the program from an already-open terminal.
