Learn how to install Python, set up your development environment, and run your first Python program on Windows, macOS, and Linux.
Learn the fundamental syntax rules of Python including indentation, comments, statements, and code structure.
Python Basics
4 topicsLearn how variables work in Python, including assignment, multiple assignment, type casting, scope, and best practices.
Learn about Python's built-in data types including numbers, strings, booleans, and None, with practical examples and type conversions.
Learn about all Python operators including arithmetic, comparison, logical, assignment, bitwise, membership, and identity operators.
Master Python string manipulation including creation, slicing, formatting, methods, and common string operations.
Control Flow
4 topicsLearn how to use conditional statements in Python including if, elif, else, nested conditions, and ternary operators.
Learn how to use for loops in Python to iterate over sequences, ranges, and other iterables with practical examples.
Learn how to use while loops in Python for repeated execution, including infinite loops, break/continue, and practical patterns.
Learn how to define and use functions in Python including parameters, return values, scope, lambda expressions, and best practices.
Data Structures
5 topicsLearn about Python lists - creating, accessing, modifying, slicing, and using list methods for data manipulation.
Learn about Python tuples - immutable sequences for storing fixed collections of data, with packing, unpacking, and named tuples.
Master Python dictionaries - key-value data structures for fast lookups, with methods, comprehensions, and practical patterns.
