- 1.Data Structures
Lists, Tuples, Sets, and Dictionaries:Understand the differences between them and when to use each.
List Comprehensions: A concise way to create lists based on existing lists or other iterable objects.
Named Tuples: Using collections.namedtuple for better data organization.
Useful when working with dictionaries, especially when you need default values for missing keys.
- 2.Object-Oriented Programming (OOP)
Classes and Objects: Understand how to define classes and instantiate objects.
Inheritance: Learn how one class can inherit properties and methods from another class.
Polymorphism: The ability to use a single interface for different data types.
Encapsulation and Abstraction: Techniques for bundling data and methods within classes and hiding implementation details.
Methods:Special methods like __init__, __str__,__repr__, __call__, etc., which allow you to customize object behavior.
- 3.File Handling
Reading and Writing Files: Work with text and binary files using open(), read(),write(), and with (for automatic file closing).
Context Managers: Use with for better handling of file operations and resources.
CSV Files: Use the csv module for reading and writing CSV files.
JSON Handling: Understand how to serialize and deserialize data with json.
- 4.Error Handling
Try/Except: Learn how to handle exceptions to prevent your program from crashing.
Custom Exceptions: Create custom exceptions to make your error-handling code more informative.
Else and Finally: Use the else block in try/except to run code when no exceptions are raised and finally to run cleanup code.
- 5.Iterators and Generators
Iterators: Learn how to use and create custom iterators using __iter__() and __next__().
Generators: Use the yield keyword to create generator functions that allow you to work with large datasets efficiently.
Generator Expressions:Similar to list comprehensions but more memory-efficient for large datasets.
- 6.Modules and Packages
Standard Library:Get familiar with Python's rich standard library (e.g., itertools,functools,datetime,os,sys,math, random, subprocess).
Third-Party Libraries: Learn how to install and use external libraries via pip, e.g., requests for HTTP requests, numpy for numerical computing, pandas for data manipulation.
Creating Modules and Packages: Organize your code into reusable modules and packages.
- 7.Decorators
Learn how to use decorators to modify the behavior of functions or methods.
Understand the concept of higher-order functions (functions that accept other functions as arguments or return them).
- 8.Lambda Functions and Functional Programming
Lambda Functions: Write small anonymous functions using lambda.
Map, Filter, Reduce: Use these functional programming tools for transforming and reducing iterables.
Functools: Dive into utilities like partial() and wraps for working with functions.
- 9.Concurrency and Parallelism
Threading: Learn how to run code in parallel using threads with the threading module.
Multiprocessing: Understand how to leverage multiple CPU cores using the multiprocessing module.
Asyncio: Work with asynchronous programming using asyncio to handle I/O-bound tasks more efficiently.
- 10.Testing and Debugging
Unit Testing: Learn how to write tests using Python’s unittest module.
Test-Driven Development (TDD): Practice writing tests before you write code.
Debugging: Use debugging tools such as pdb and IDE debuggers to track down and fix bugs in your code.
- 11.Advanced Functions
Closures: Understand how inner functions can remember and access variables from their enclosing scope.
Function Arguments: Explore variable-length argument lists using *args and **kwargs.
Recursive Functions: Understand how recursion works and practice solving problems recursively.
- 12.Working with Databases
SQLite: Learn to use SQLite in Python for small-scale database applications.
SQLAlchemy: Use SQLAlchemy as an Object-Relational Mapping (ORM) library for managing database interactions.
ORM Basics: Learn how to interact with databases in an object-oriented way.
- 13.Regular Expressions
Learn how to use Python's re module to match patterns in strings and extract or replace text.
- 14.Web Development Basics (Optional but useful)
Flask/Django: Explore web frameworks like Flask or Django to develop web applications.
APIs: Learn how to make API requests using libraries like requests or build APIs with Flask.
- 15.Best Practices
PEP 8:Follow Python's official style guide for writing clean, readable code.
Code Reviews: Practice reviewing others' code and participating in collaborative coding environments.
Version Control with Git: Understand how to use Git for version control in software development.
Next Steps
Build Projects: Work on real-world projects (e.g., web apps, data analysis projects, automating tasks) to reinforce your knowledge.
Contribute to Open Source: Get involved with open-source projects to learn from others and practice your skills in a real-world context.
Example Project Ideas for Practice:
To-Do List Application: Build a console-based to-do list app with file handling.
Web Scraper: Use libraries like BeautifulSoup or Scrapy to scrape data from websites.
Flask Web App: Create a simple web application using the Flask framework.
Chatbot: Build a basic chatbot that can respond to user input intelligently.
