Question

How to stop the window from closing once a program has been executed in python?
Do i have to add some keyword in the program or something??

Answer 1

there's a couple things you can do. the first is to launch Idle and then open your script with Idle and run it.

or you can open a command prompt in your script's directory and type "python myscript.py" (you may need to set your Environment vaiables if on Windows to do it this way, btw). see here: http://www.youtube.com/watch?v=IokKz-LZsEo

now, if you want to be able to double click it, you should add something like this to the last line of your program:
raw_input('PRESS RETURN TO CLOSE')
this will wait for user input before ending the program

Answer 2

You can right click the file, and choose "Edit with IDLE", then choose the Run from menu, and then Run Module( or just use F5 as a quick-button ), as you do this, you'll see the result in the python shell, and that'll never close.

Answer 3

You could also open a command prompt (assuming you're in Windows it would be CMD in the run box) and simply type python file.py (assuming you've setup your path to include Python).
