Welcome back to our OCR GCSE Computer Science (J277) revision series! Today we are tackling "Array Processing" in Python. The exam board loves to ask you to iterate through an array to find specific values or calculate totals.
Interactive Challenge: For each of the 5 questions on our custom mock paper, I want you to PAUSE the video, open your Python editor, and try to code the answer yourself. After each question, we will walk through the solution and the official mark scheme!
We will cover:
- Q1 (4 Marks): Finding the MAXIMUM value in an array.
- Q2 (4 Marks): Finding the MINIMUM value in an array.
- Q3 (3 Marks): Calculating the SUM (running total) of an array.
- Q4 (4 Marks): Calculating the AVERAGE of an array using `len()`.
- Q5 (4 Marks): Using a conditional `IF` statement to COUNT specific items in an array.
