Ok I am confused. I just started python and when I save my program that I edited in the IDE editor as for example helloworld.py I cannot run it when I click it. All it does it come up with a black box, like cmd, and dissappears. Also do you have to have python to run your program? Say you make some kind of software do you have to have python? Also what is the difference between the python shell in IDE and the editor in IDE. Also what is the Python (command line) for and why do you need it?
