JES is a programming environment that you can use to write and run Python programs. You can use JES to edit photos, videos, and sound, and it is also a powerful tool that can help you test and debug your code.

Like any programming environment, there are times when you may need some help or guidance. You can access help for built-in JES functions by using the JES help system.

This allows you to access information about each function such as what their parameters are, and what value the function returns.

How to Find Help for Built-In Functions Using the Help Window

JES includes many useful built-in functions that can help with many tasks. These include creating graphics in JES, rendering images in JES before editing them, and more.

You can find help for built-in functions by accessing the help window inside the JES application.

  1. Open the JES software on your computer.
  2. At the top of the application window, click on the JES Functions tab. JES separates each function into different categories. These are colors, files, input/output, turtles, movies, pixels, pictures, and sound. Hover over a category to view the names of all available built-in functions.

How to Find Help for Functions Used in the Programming Area

If you are already using a function inside the programming area, you can open the help page for that function by selecting it.

  1. Inside the programming area, add some code that uses JES's built-in functions. Make sure to revise basic Python commands and syntax if needed. For example:
            def getHeightOfPicture():
      file = pickAFile()
      pic = makePicture(file)
      height = getHeight(pic)
      print height
  2. Select a function by putting your cursor on top of a function name, such as getHeight(), and clicking on it.
  3. At the bottom of the JES application window, click on the Explain getHeight button.
