Line-by-line explanation
- Line 1 sets up the Train Test Split example: rows = [.
- Line 2 adds one required part of the working pattern: {"hours": 1, "score": 45}, {"hours": 2, "score": 52},.
- Line 3 adds one required part of the working pattern: {"hours": 3, "score": 63}, {"hours": 4, "score": 70},.
- Line 4 adds one required part of the working pattern: ].
- Line 5 adds one required part of the working pattern: train, test = rows[:3], rows[3:].
- Line 6 adds one required part of the working pattern: average_score = sum(row["score"] for row in train) / len(train).
Why this example is useful
