  • professor.py: Math quiz generator.

Week 5: Unit Testing

• Concepts: Writing and running tests with pytest, test-driven development, and code coverage.
• Sample Projects:
  • test_bank/, test_fuel/, test_plates/, test_twttr/: Automated tests for previous weeks' projects.
  • _practice/calculator/: Simple calculator with tests.

Week 6: File Handling & CSV

• Concepts: Reading/writing CSV files, working with data, and file manipulation.
• Sample Projects:
  • lines.py: Count lines in a file.
  • pizza.py: Read pizza menu from CSV.
  • scourgify.py: Clean up CSV data.
  • shirt.py: Overlay images using PIL.

⚙️ USAGE

1. Clone the repository:

   git clone https://github.com/maitreverge/CS50P.git

2. Navigate to the project directory:

   cd CS50P

3. (Optional) Set up a Python virtual environment:

   source ./p_env.sh master

Note

The p_env.sh script manages Python virtual environments and dependencies. For help, run: ./p_env.sh -h

4. Run any script:

   python week_X/project_name/project.py

   Replace X and project_name as needed.

🗂️ PROJECT STRUCTURE

• week_0/ to week_8/: Weekly folders with projects and exercises.
• img/: Images and assets for documentation.
• requirements.txt: Python dependencies.
• p_env.sh: Virtual environment setup script.
