1. Open repository in codespaces
2. Create a branch of this repository. Use your first name as the name of the branch. You may use the UI, or this command git checkout -b YOUR_NAME
3. Create a new file, solution.py, in the root directory of this repository that you will use to write your code.
4. Write a python function that reads in presidents.json in the root of this repository and computes the average age of each of the people in the file.
5. Edit presidents.json to add a new president. Rerun your function to make sure it prints the age of the new president.
6. Edit the presidents.json file to add a new column for state of birth.
7. Write a python function that reads in your new presidents.json and prints out all of the presidents sorted by state.
