Python for Beginners [2025]: Zero to Hero

Install python and set up an ide by downloading the latest python 3.13.1 from python.org, enable add python to path, and verify with python --version in the command prompt.

Install and configure PyCharm to run Python scripts, create a project named Learn Python, set up a source directory and hello.py, write and run hello world to verify the interpreter.

Explore input and output in Python, using the input function and print, and perform data type conversions to integer, float, and boolean for dynamic user interactions.

Explore Python variables and data types, learn how to store and print values, inspect types, and perform multi-variable assignments and simple swaps with tuple unpacking.

Define tuples in Python, an immutable, ordered collection similar to lists. Access by index, concatenate to form new tuples, and print results to observe immutability.

Explore lists as mutable, ordered collections that store mixed types, and learn to create, print, access by zero-based indices, and perform append, remove, slicing, and replacement by index.

Define dictionaries as mutable collections of unique keys mapping to values, and learn to create, print, access by keys, and update or remove key-value pairs.

Explore Python sets as unordered collections of unique, immutable elements and learn core operations like add, remove, union, intersection, and difference with practical examples.

Explore arithmetic, comparison, logical, assignment, membership, and identity operators in Python as you build expressions with variables and print results.

Explore Python string operators, including concatenation, repetition, comparison, membership, and slicing, with practical examples that show how to build and inspect strings using unicode-aware comparisons.

Master Python program flow with if, elif, and else, and repeat actions using for and while loops. Apply logical operators and control statements like break, continue, and pass.

Learn how to use Python logical operators and, or, and not to combine conditions, with practical examples like age and citizenship and test cases showing true and false results.

Learn to write Python loop statements, including for and while loops, to repeat code over sequences or until a condition changes, using range to drive iterations and print results.

Learn how break, continue, and pass control loop execution in Python. Use break to exit loops, continue to skip iterations, and pass as a placeholder, with practical examples.

Define and call functions in Python using def, pass parameters and arguments, return values, and use default parameters with examples like say hello and greet.

Learn how to identify and handle Python exceptions, including zero division error, type error, index error, and file not found error, using try, except, else, and finally blocks.

Learn object oriented programming in Python by defining classes, creating objects, and using attributes. Explore inheritance, polymorphism, encapsulation, and the difference between instance and class attributes with car examples.

Explore how inheritance in Python lets a child class inherit attributes and methods from a parent class, using super to initialize shared attributes like brand, speed, and fuel type.

Explore polymorphism in Python by comparing a vehicle and a car class that share the same show info method. The car overrides the method and uses super for customization.

Master encapsulation in Python by using private attributes with double underscore and getter and setter methods to control access in a vehicle and car class hierarchy.
