Graphical User Interface You will be used to using programs that have a graphical user interface (GUI). So far you have been writing programs that have a command line interface (CLI). Now you are going to learn how to develop programs with a GUI using Python. Python uses a library or ‘add-on’ called Tkinter to create GUIs.

Task 1 Start a new Python program and enter the code shown below: Creates a new text box containing the text “Computer”. Add the text box to the screen.

Task 2 Add these three lines of code to your program. What do the new lines do?

Task 3 Start a new Python program and enter the code shown below: Adds a text entry box to the screen. This function is called when the button is pressed. Adds a button to the screen.

Task 4 Start a new Python program and enter the code shown below: The inputted numbers are converted to integers for the calculation.
