You are required to develop a Python program that processes a list of student scores and generates a grade report. The grading scale is: A: 70‑100, B: 60‑69, C: 50‑59, D: 45‑49, E: 40‑44, F: 0‑39. The scores are stored in a text file named "scores.txt" where each line contains a student's name and their score separated by a comma (e.g., "Ada,85").

Question Parts

( a )
Write a Python function called `grade_counts(scores)` that takes a list of integer scores (0‑100) and returns a dictionary whose keys are the grades ("A", "B", "C", "D", "E", "F") and whose values are the number of occurrences of each grade.
( b )
Using the function from part (a), write a complete program that: i) Reads the file "scores.txt". ii) Extracts each student's name and score, ignoring any line that does not contain a valid name‑score pair. iii) Calls `grade_counts` to obtain the grade distribution. iv) Writes the distribution to a new file "grade_report.txt" in the format "A: 5" (one grade per line). v) Prints on the screen the total number of students whose records were processed. Include appropriate error handling for missing files and malformed lines.
