Running Python as a subprocess of Python is almost never the correct solution. If you do go with a subprocess, you should avoid Popen unless the higher-level functions really cannot do what you want. In this case, check_call or run would do everything you need and more, with substantially less plumbing in your own code. –

Oct 13, 2009 · I've looked at the timeit module, but it seems it's only for small snippets of code. I want to time the whole program. $ python -mtimeit -n1 -r1 -t -s "from your_module import main" "main()" It runs your_module.main() function one time and print the elapsed time using time.time() function as a timer.

This code will run as a daemon and is effectively like calling the python script every minute using a cron, but without requiring that to be set up by the user. In this question about a cron implemented in Python , the solution appears to effectively just sleep() for x seconds.

Sep 25, 2013 · As per strictest interpretation of the question "continue even if there's an exception". Python gives us a keyword "finally" which executes a block of code no matter what precedes it. The only issue with this method will run a block of code regardless of the type of error, which might not be desirable for all cases.

Note on Python version: If you are still using Python 2, subprocess.call works in a similar way. ProTip: shlex.split can help you to parse the command for run, call, and other subprocess functions in case you don't want (or you can't!) provide them in form of lists: import shlex import subprocess subprocess.run(shlex.split('ls -l'))

If the input is 'y', the outer while loop starts again (continue keyword skips the remaining code and goes straight to the next iteration). If the input is 'n', the outer while loop breaks and the program ends. Note: I'm using input() in Python 3. In Python 2, use raw_input().

[Done] exited with code=1 in 0.034 seconds. It's a very simple Hello, World! program that doesn't really need much. Why is Visual Studio Code not letting me run a Python file? This is where my Python executable is stored: C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python36_64\python.exe

Apr 27, 2022 · The button just runs the file in a Python terminal, the default command associated with Ctrl+F5 will run the file in the Python debugger, just with the debugging turned off. – Ajean Commented Nov 22, 2023 at 18:04

Jun 8, 2018 · The asynshonous equivalent on the other hand looks somting like this took three seconds to run as opposed to nine secounds. The first count cycle was started and as soon as it hit the awaits sleep one Python was free to do other work, for instance starting the secound and subsequently the third count cycles. This is why we have all the ones ...

It is always an option to enter python on the command line with the command python. then import your file so import example_file. then run the command with example_file.hello() This avoids the weird .pyc copy function that crops up every time you run python -c etc.
