Python: Stop Auto Exiting Cmd Prompt

Question

So I just started learning Python and just now set up my Notepad++ to run it via cmd prompt. Is there a simple way to stop my cmd prompt from auto-exiting when I run a simple program? Do I need to ask for input every time or something or is there an easier way?

I tried raw_input('Press Enter to exit') but no luck.

Here's the program my introduction to python book started me with http://pastebin.com/ZVJrUzZZ

If it makes any difference I'm running it straight to python.exe in python version 3.2

Answer 1

What I personally like to do is have the Python script just run to completion without asking for input, then write a batch file (Windows) or shell script (Linux/UNIX) to do the "press any key" thing. That way when I run the script from the command line it doesn't needlessly prompt me for input.

You could write a batch file like this:

python.exe %*
pause

Save it as pypause.bat and tell Notepad++ to run your Python scripts via this batch file instead of through python.exe .

Answer 2

You have the right idea. You would need to put something like raw_input() somewhere before the script exits.

If this is python 3, use input instead of raw_input :

if __name__ == '__main__':
    print(approximate_size(1000000000000, False))
    print (approximate_size(1000000000000))

input('Press Enter to exit')
