How to determine if Python script was run via command line?

Question

Background

I would like my Python script to pause before exiting using something similar to:

raw_input(\"Press enter to close.\")

but

Answer 1

Okay, the easiest way I found and made was to simply run the program in the command line, even if it was ran in the Python IDLE.

exist = lambda x: os.path.exists(x)    ## Doesn't matter

if __name__ == '__main__':

    fname = "SomeRandomFileName"    ## Random default file name

    if exist(fname)==False:         ## exist() is a pre-defined lambda function
        jot(fname)                  ## jot() is a function that creates a blank file
        os.system('start YourProgram.py')    ## << Insert your program name here
        os.system('exit'); sys.exit()   ## Exits current shell (Either IDLE or CMD)

    os.system('color a')            ## Makes it look cool! :p
    main()                          ## Runs your code
    os.system("del %s" % fname)     ## Deletes file name for next time

Add this to the bottom of your script and once ran from either IDLE or Command Prompt, it will create a file, re-run the program in the CMD, and exits the first instance. Hope that helps! :)
