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   This would just show a cursor with no text   raw input      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    raw input        Note     1  In python 3  there is no raw input    just   input       2  Use single quotes to indicate a string  otherwise if you type doubles around anything  such as    raw input     it will think it is a function  variable  etc  and not text    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   input     Hopefully this helps others who might be starting out and still haven t figured out how the computer thinks yet  It can take a while   o

Apart from input and raw input  you could also use an infinite while loop  like this  while True  pass  Python 2 5  3  or while 1  pass  all versions of Python 2 3   This might use computing power  though   You could also run the program from the command line  Type python into the command line  Mac OS X Terminal  and it should say Python 3      Your Python version  It it does not show your Python version  or says python  command not found  look into changing PATH values  enviromentl values  listed above  type C   Python folder python exe  If that is successful  type python or C   Python installation  python exe and the full directory of your program

A very belated answer  but I created a Windows Batch file called pythonbat bat containing the following   python exe  1  echo off echo  pause   and then specified pythonbat bat as the default handler for  py files   Now  when I double-click a  py file in File Explorer  it opens a new console window  runs the Python script and then pauses  remains open   until I press any key     No changes required to any Python scripts   I can still open a console window and specify python myscript py if I want to      I just noticed  maurizio already posted this exact answer

You have a few options    Run the program from an already-open terminal  Open a command prompt and type   python myscript py   For that to work you need the python executable in your path  Just check on how to edit environment variables on Windows  and add C  PYTHON26  or whatever directory you installed python to    When the program ends  it ll drop you back to the cmd prompt instead of closing the window  Add code to wait at the end of your script  For Python2  adding      raw input         at the end of the script makes it wait for the Enter key  That method is annoying because you have to modify the script  and have to remember removing it when you re done  Specially annoying when testing other people s scripts   For Python3  use input    Use an editor that pauses for you  Some editors prepared for python will automatically pause for you after execution  Other editors allow you to configure the command line it uses to run your program  I find it particularly useful to configure it as  python -i myscript py  when running  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
