  • Single and Multiple Inheritance
• Polymorphism
• Encapsulation and Abstraction
• Special Methods: str, repr, len, etc.

• Class Methods and Static Methods
• Composition vs. Inheritance
• Abstract Base Classes (ABCs)

6. Error Handling

• Types of Errors: Syntax, Logic, Runtime
• try, except, finally blocks
• Raising Exceptions with raise
• Custom Exception Classes
• Using assert for Debugging
• Logging Errors with the logging Module
• Creating Context Managers for Error Handling
• Best Practices in Error Handling

7. File Handling

• Opening Files: open(), read(), write()
• Reading and Writing to Files
• File Modes (r, w, a, b)
• Working with File Paths
• Using with to Automatically Close Files
• Reading and Writing CSV Files
• Working with JSON Files
• File Iterators
• Handling Large Files with Buffered Reading/Writing

8. Modules and Packages

• Importing Modules: import, from ... import
• Python Standard Library (e.g., math, random, datetime)
• Creating and Using Custom Modules
• Using Third-Party Packages with pip
• Virtual Environments
• Understanding the __init__.py file
• Building Your Own Package
• Using requirements.txt for Dependency Management
• Exploring the sys and os Modules

9. Working with Libraries

• NumPy (for array manipulation)
• Pandas (for data analysis and manipulation)
• Matplotlib and Seaborn (for data visualization)
• Requests (for handling HTTP requests)
• JSON Handling
• Using SciPy for Scientific Computing
• Working with SQLAlchemy for Database Interaction
• Web Scraping with Beautiful Soup and Scrapy
• Introduction to TensorFlow and Keras for Machine Learning

10. Advanced Topics

• List and Dictionary Comprehensions (advanced usage)
• Generators and yield keyword
• Decorators and @decorator_name
• Context Managers
• Regular Expressions (Regex)
• Unit Testing with unittest
• Metaclasses and their Use Cases
• Asynchronous Programming (async/await)
• Threading and Multiprocessing
• Python’s functools module (e.g., lru_cache, partial)
• Descriptors and Property Decorators
• Type Hinting and Annotations
• Advanced Error Handling and Custom Exceptions

11. Working with APIs

• What are APIs?
• Consuming APIs with Python
• Authentication (Basic, OAuth)
• Parsing JSON from APIs
• Using the requests Library for API Calls

• Data Cleaning Techniques
• Understanding Overfitting and Underfitting

13. Final Project

• Develop a Python project that integrates different concepts:
  • Data Analysis, Web Scraping, or a Simple Game
• Project Planning and Documentation
• Version Control with Git
• Deployment Options (e.g., Heroku, GitHub Pages)
