Pause in Python

Question

I am running command-line Python scripts from the Windows taskbar by having a shortcut pointing to the Python interpreter with the actual script as a parameter   After the script has been processed  the interpreter terminates and the output window is closed which makes it impossible to read script output   What is the most straightforward way to keep the interpreter window open until any key is pressed   In batch files  one can end the script with pause  The closest thing to this I found in python is raw input   which is sub-optimal because it requires pressing the return key  instead of any key    Any ideas

One way is to leave a raw input   at the end so the script waits for you to press enter before it terminates    The advantage of using raw input   instead of msvcrt   stuff is that the former is a part of standard Python  i e  absolutely cross-platform   This also means that the script window will be alive after double-clicking on the script file icon  without the need to do   cmd  K python  lt script gt

In Windows  you can use the msvcrt module       msvcrt kbhit         Return true if a keypress is waiting to be read       msvcrt getch         Read a keypress and return the resulting character  Nothing is echoed   to the console  This call will block   if a keypress is not already   available  but will not wait for Enter   to be pressed    If you want it to also work on Unix-like systems you can try this solution using the termios and fcntl modules

There s no need to wait for input before closing  just change your command like so   cmd  K python  lt script gt    The  K switch will execute the command that follows  but leave the command interpreter window open  in contrast to  C  which executes and then closes
