Yêu cầu
- Basic Python programming knowledge: Understanding of Python data types, functions, classes, and syntax is essential for following the tutorial.
- Familiarity with SQL: Learners should have a basic understanding of SQL concepts like tables, primary keys, foreign keys, and CRUD operations (Create, Read, Update, and Delete).
- Object-Oriented Programming (OOP) understanding: Since the tutorial uses Object Relational Mapping (ORM) for creating tables, having some experience with OOP and Python classes would be beneficial.
- Python environment: Learners should have a Python development environment set up on their machine (Python 3.x and pip) or have access to a Jupyter Notebook environment where they can install packages and run code snippets as demonstrated in the tutorial
- Database access: Access to a PostgreSQL database server for hands-on practice is crucial. Familiarity with creating databases and user accounts would be useful but not required, as it can be learned along the way.
