What this example teaches
Linear Regression
Output
The script reads or transforms sales rows and status values and prints a result you can verify.
Line-by-line explanation
- Line 1 sets up the Linear Regression 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
This example is useful because it isolates linear regression without surrounding noise, so you can see the idea clearly.
Where it is used in real projects
Linear Regression appears in real Python work when a feature needs a clear pattern that can be reviewed and changed safely.
Beginner variation
Change one label, value or condition in the Linear Regression example and run it again.
Advanced variation
Combine Linear Regression with validation, error handling or reusable structure.
