Improve Python CodeIn Part 2, you will learn how to write better ChatGPT scripts and create simple Python programs.
The most important idea in this part is that Python code should not appear by magic.
You first write a clear script for ChatGPT.
Then ChatGPT generates Python code.
Then you review, test, and improve the code.
Learning Objectives
After completing this part, you will be able to:
Course Coding Standard
Starting in this part, every Python program should include a clear header at the top.
The header should include:
- Program name
- Purpose
- User ChatGPT script
- Expected output
- Version
- Notes for the student
The code should also be divided into steps.
Example step labels:
# ============================================================
# STEP 1 - Ask for User Input
# ============================================================This makes the program easier to understand, test, and improve.
Standard ChatGPT Script Requirement
Whenever you ask ChatGPT to write Python code, include this section:
Coding Standards:
1. Add a detailed program header at the top of the Python file.
2. The header must include:
- Program Name
- Purpose
- User ChatGPT Script
- Expected Output
- Version
3. Divide the Python code into clearly labeled steps.
4. Add comments explaining every important line.
5. Make the code suitable for beginners.
6. Explain how to run the code in VS Code.Chapter 1 - Writing Better ChatGPT Scripts
Objective
Learn how to write prompts that generate useful Python code.
A vague prompt gives weak code.
A clear ChatGPT script gives better code.

Poor ChatGPT Script
Write a Python program.This is too vague.
It does not tell ChatGPT:
- What the program should do
- What files or folders are used
- What output is expected
- Whether comments are needed
- Whether the code should be beginner friendly
