Program Plan Intro
Tree Age
Program Plan:
- • Import “Tkinter” module for creating the GUI programs.
- • Define the necessary named constants for creating the growth rings.
- • Define the class named “Treeclass”.
- ○ Define “__init__()” method for “Treeclass” class:
- ■ Create the main window using the “tkinter” module.
- ■ Create a canvas widget.
- ■ Create the ring1 using canvas widget using the “create_oval()” method.
- ■ Specify the text on the ring created using the canvas widget using the “create_text()” method.
- ■ Create the ring2 using canvas widget using the “create_oval()” method.
- ■ Specify the text on the ring created using the canvas widget using the “create_text()” method.
- ■ Create the ring3 using canvas widget using the “create_oval()” method.
- ■ Specify the text on the ring created using the canvas widget using the “create_text()” method.
- ■ Create the ring4 using canvas widget using the “create_oval()” method.
- ■ Specify the text on the ring created using the canvas widget using the “create_text()” method.
- ■ Create the ring5 using canvas widget using the “create_oval()” method.
- ■ Specify the text on the ring created using the canvas widget using the “create_text()” method.
- ■ Pack the canvas that is created using the “pack” method.
- ■ Call the main loop using the “tkinter” module.
- • Now, call the “Treeclass()” function.
- ○ Define “__init__()” method for “Treeclass” class:

Counting the growth rings of a tree is a good way to tell the age of a tree. Each growth ring counts as one year. Use a Canvas widget to draw how the growth rings of a 5-year-old tree might look. Then, using the create_text method, number each growth ring starting from the center and working outward with the age in years associated with that ring.

Method: addOneMinute()
Description: This method adds one minute to the current time.
Method Signature: void addOneMinute()
Parameters: This method does not take any parameters.
Return Value: This method does not return anything.
Instructions:
Check the value of getMinute(). If it is between 0 and 58 inclusive, add 1 to it and call setMinute() with the new value.
If getMinute() is 59, set minutes to 0 by calling setMinute(0), and then call addOneHour() to add one hour to the time.
Note: You may change things around in your program, but for now please make this method work with the existing method signatures.

Magic 8 Ball Lab
Introduction For this lab, you are going to build a simple magic eight-ball, so you no longer have to make any choices. On that note, if you haven’t, you should watch Interstate 60. All joking aside, you will build a 15 sided magic 8-ball, just for simplicity (an actual one has 20 sides for choices). If you are curious about all the choices, you can read up more on them here. Also, if you need a refresher on if statements, go here. Step 1 - Reading the code First take a look at the provided code. You should change the comments to include your name at the top of the file. Furthermore, you will notice all the functions are ‘stubbed’ out for you. This means we have provided the function signature, and a dummy return value that you will replace completely. We have also provided one function in its entirety, so you can use it as a sample/template to look at.
