Introduction To Python Programming

Explore variables in Python, learn to store data, create a string variable, and use multiple assignment to assign values to several variables at once.

Learn how Python applies arithmetic operators to integers and strings—addition, subtraction, multiplication, division, and modulus—plus string concatenation and repetition. Explore slicing and indexing that starts at zero to extract substrings.

Explore placeholders in strings and formatting in Python, including percent-based placeholders like %s and %d, and the modern f-strings introduced in Python 3.6 for concise, readable code.

Explore Python lists, including creation, zero-based indexing, slicing, and updating items. Learn to append, delete, and perform list operations like concatenation and max and min.

Learn how Python dictionaries map unique keys to values, access data by key, update entries, and delete items using del, plus counting entries with len and ensuring unique keys.

Explore tuples in Python, the immutable data structure with parentheses, indexing, and slicing. Learn how concatenation lets you create new tuples and how their immutability maintains data consistency and safety.

Explore conditional statements in Python with if-else logic, indentation, and relational operators that determine true or false. Use elif and logical operators to handle multiple conditions and comparisons.

Master for loops in Python to iterate over lists and tuples, print items, and use range for numbered sequences, including stepping and nested loops.

Master while loops in Python programming, learning how a condition governs iteration and how break, continue, and pass control the loop flow.

Learn how to use Python's try and accept statements to handle exceptions, using examples like undefined names and API calls, and compare the try block with accept block on error.

Learn how to define and call reusable Python functions using def, parameters, and return statements. Explore examples like printing greetings, adding numbers, and composing functions.

Explore Python’s built-in functions, including abs for absolute value, bool for truthiness, dir for object methods, and help, eval, and exec, plus str, int, and float conversions.

Explains how classes serve as blueprints and objects as instances with attributes and behaviors, while the init method and self enable reusability and organization in code.

Explore inheritance in Python by modeling a base car class and a sports car subclass, showing shared attributes, the drive method, overridden behavior, and the role of super in init.
