The Ultimate Python Developer Course: Learn Step by Step

Explore Python operators and expressions to perform mathematical calculations—addition, subtraction, multiplication, division, and modulus—and learn comparison and operators such as greater than, equal, not equal, and, or, not.

Learn how to take user input with Python's input function, format and display output, and read from and write to files using open, write, and read operations.

Master for loops over lists and ranges, and while loops in Python. Iterate sequences, print results, and control repeated execution.

Explore Python iterators and generators through practical, example-driven explanations. See how next and yield power custom iterators and generators.

Learn how list comprehensions replace loops to create squares and even numbers, with conditions, and how lambda functions provide small functions, including using map to apply lambdas to numbers.

Explore how to define and call functions in Python, create reusable blocks of code, and use parameters and return values to build readable programs.

Explore recursion in Python, defining functions that call themselves with a base case and a recursive case, illustrated by factorial, Fibonacci, sum, and power examples.

Explore importing and creating modules in Python, from built-in math and random modules to custom modules, and learn using specific functions over star imports for cleaner code.

Learn Python's lists, tuples, and sets, including ordering and mutability, immutability of tuples, and sets hold unique items; practice adding, removing, indexing, membership checks, and duplicate removal.

learn to implement stacks, queues, and linked lists in python, including push and pop on stacks, enqueue and dequeue on queues, and building and displaying a linked list.

Explore how Python constructors initialize objects and how destructors clean up resources during an object's life cycle, with hands-on examples using class attributes and models.

Learn to read and write csv and json files, and build pipelines for storing and transforming tabular and dictionary data.

Learn to handle exceptions and errors in Python with try-except and finally blocks, covering syntax errors and runtime exceptions, preventing crashes and delivering friendly error messages.

Learn how to use the os and shutil modules in Python to interact with the operating system, create and rename directories, list directory contents, and copy or move files.

Define what a database is and compare relational, NoSQL, and cloud databases, with MySQL and PostgreSQL examples; learn about database management systems and core SQL concepts (DDL, DML, DCL, TCL).

Perform CRUD operations—create, read, update, and delete—using sqlite3 in Python, including connecting to an SQLite database, creating a students table, and executing inserts, selects, updates, and deletes.

Learn to use Python's re module to search text, find patterns, and extract emails, then replace numbers and redact data with regex.
