Writing a function for strings
In chapter 2, you wrote a script to process a student's grades. Now you have a lot of students' grades to process, so it's time to write a function for it.
For each student, you have text data that looks like this:
grades = "XXXX"
Where the letters "XXXX"
are the grades for the student in mathematics, history, science, and drama, respectively.
A single string of grades named mygrades
and an array of grade strings named grades_array
is available in your environment.
