I have updated the assignment_2 file with the needed code to solve all the required pieces

What did you learn from the changes you have made?

 I have learned the following:
 1. GitHub commands 
 2. making a new branch on GitHub
 3. functions in python
 4. how to pass parameters to a function
 5. how to deal with files 
 6. how to read files
 7. NumPy package usage
 8. How to test output if they are logic or not

Was there another approach you were thinking about making? If so, what approach(es) were you thinking of?

 The approach inside the assignment file is ok for me and logic

Were there any challenges? If so, what issue(s) did you face? How did you overcome it?

 NumPy package was not installed in my environment,
 I searched google and figured out how to install it.

How were these changes tested?

 By Looking at the output of each execution.
