Python 3 Mastery Course

An introduction to Python, what it is, why you should learn it, how its syntax compares to other languages, and its various real-world applications.

Learn how to install Python, set up your development environment, write your first script, and run Python from the command line.

Understand the core syntax of Python, including indentation rules, single-line and multi-line comments, line continuation, and case sensitivity.

Master variables in Python: how to create them, naming rules, assigning multiple values, understanding scope, and using constants.

Explore the built-in data types in Python, including strings, numbers, sequences, mappings, sets, and booleans, and learn how to check variable types.

Learn about Python's built-in numeric types: int, float, and complex. Understand type conversion and how to generate random numbers.

Understand how to cast variables in Python. Learn the difference between implicit and explicit casting and when to use them.

Master string manipulation in Python. Learn about literals, indexing, slicing, concatenation, string methods, formatting, and escape characters.

Discover Python Booleans: understanding True and False values, comparison operators, the bool() function, and falsy values.

A comprehensive guide to Python operators: arithmetic, assignment, comparison, logical, identity, membership, and bitwise operators.

Everything you need to know about Python Lists: creating, accessing, modifying, adding, removing, and iterating over lists.

Understand Tuples in Python. Discover how they differ from lists, how to access them, unpack them, and their specific methods.

Learn how to use Python Sets. Sets are unordered collections with no duplicate items. Learn how to add, remove, and join them.

Master Python Dictionaries. Learn how to store data in key-value pairs, access, modify, add, and remove items, and work with nested dictionaries.

Control flow in Python using conditional statements: if, elif, else, nested statements, and logical operator integrations.

Learn how to execute code repeatedly as long as a condition is true using Python's while loops, and control them using break and continue.

Master Python for loops. Learn how to iterate over sequences, use the range() function, nested loops, and control flow within loops.

Learn how to write reusable code in Python using functions. Covering arguments, default parameters, return values, and variable-length arguments.

Master Python Lambda functions: anonymous, single-line functions perfect for short operations or passing as arguments to higher-order functions.

Learn about Python Arrays. Understand the difference between Lists and Arrays, how to import the array module, and manage array elements.

Dive deep into Object-Oriented Programming (OOP) in Python. Master classes, objects, inheritance, encapsulation, and polymorphism.

Understand the core of Python iteration. Learn about iterators, iterables, __iter__, __next__, and the StopIteration exception.

Learn how to use generators in Python. Understand the yield keyword, generator expressions, and how they save memory.

Master Python decorators. Learn how to modify the behavior of functions dynamically using the @ syntax, nested functions, and first-class objects.

Understand the concept of variable scope in Python. Learn about local, global, nonlocal keywords, and the LEGB rule.

Learn how to organize your Python code into modules. Discover how to create, import, and use built-in modules.

Understand Python packages: how to organize multiple modules into directory hierarchies using __init__.py files.

Work with dates and times in Python using the datetime module. Learn how to format strings to dates and perform date arithmetic.

Perform mathematical operations in Python. Explore built-in functions, the math module, and operations on complex numbers.

Learn how to parse, manipulate, and generate JSON data in Python using the built-in json module.

Master text matching and manipulation using Regular Expressions in Python via the re module.

Learn how to use PIP, the standard package manager for Python, to install, manage, and distribute third-party libraries.

Master error handling in Python using try, except, else, and finally blocks. Learn how to catch exceptions and raise custom ones.

Learn how to work with files in Python: opening, reading, writing, and appending data securely using context managers.

Interact with users via the command line using the input() and print() functions, and format your output beautifully.

Learn how to read and write Comma Separated Values (CSV) files using Python's built-in csv module.

Master API integration in Python. Learn how to make GET and POST requests, handle JSON responses, and manage errors using the requests module.

Learn why virtual environments are essential in Python, and how to create, activate, and manage them using the venv module.

Ensure your code works flawlessly. Learn the basics of Python testing using the built-in unittest module and the popular pytest framework.

Apply what you have learned! Build practical, real-world Python projects including a calculator, web scraper, weather API, and more.

A comprehensive quick-reference guide for Python's built-in functions, methods for various data types, exceptions, and key modules.
