Now that we have imported libraries, initialized pygame, and created globals for colors, the screen, ball, and the paddles, we can run our first tests to check how things are going. To test the game, you will need to locate the directory where you saved your tiny.py file in your terminal/command prompt. In earlier games, we made this directory on the desktop. Once you navigate to the directory where tiny.py is saved, you can run the following commands from the terminal/command prompt to see your game so far:

  python tiny.py

When you run this command, you should see a window pop up and then close. The window will not stay open because we have not written any of the code that runs the game; however, if the code runs and there are NO ERRORS in your terminal/command prompt, then you can keep moving forward with confidence.

If there are errors in your code, now is a good time to fix them. Some common errors that can take place include syntax errors (using the wrong symbols),...
