Mastering Python : From Zero to Vibe-Code to OOP

Master the python for loop by using for variable in sequence with indentation. Learn how range generates integers to print 1 to 5, and loop over fruits.

Learn how to implement for and while loops in Python, control flow with break and continue, use range, and iterate over dictionaries by items, keys, and values.

Learn to implement a password check with a while loop and conditionals, handling limited attempts, printing incorrect password messages, and granting access when the correct password is entered.

Learn to automate daily tasks with loops, using for and while loops to filter inboxes, monitor kettle temperature, and compile a master grocery list from a weekly meal plan.

Explore Python functions and lambdas, learning why functions automate repetitive tasks, organize code, and enable reuse; master the syntax with def, calling, and returning values through practical examples.

Explore how functions return values using a Coca-Cola vending machine example. Implement a get Coca-Cola function that takes coin input, checks valid coins, and returns the corresponding can.

Define a celsius-to-fahrenheit converter using Fahrenheit equals Celsius times 9/5 plus 32, then reverse a string with the slicing trick S[::-1] to explore start, stop, and step.

Explore how functions handle multiple inputs, such as rectangle area (length times width) and an emi calculator, including user input conversions, return values, and rounding emi to two decimals.

Explore why lambda functions are used for filtering data with pandas data frames, sorting by a custom key, and quick maths, and learn when to use full functions instead.

Master python exception handling with try-except blocks, learn the common errors like zero division, file not found, value error, type error, and key error, and how to handle them.

Learn file handling and error handling with try-except blocks in Python, address file not found, value errors, zero division, multiple except blocks, and use finally to run the final block.

Explore class attributes versus instance attributes with a car example, defining wheels as a class attribute before __init__, creating objects, and accessing brand, model, and wheels.

Explore modifying instance and class attributes in Python by changing car1's brand to Tesla and updating car1 and car2 wheels to 6, demonstrated in a Jupyter notebook.

Explore inheritance in Python by comparing parent and child classes, using Venn diagrams to illustrate concepts, and learn single and multiple inheritance with practical attribute and method transfer.

Demonstrates single inheritance in Python by modeling a bank account system with a general account and a savings account. Uses super to pass owner and balance and adds interest rate.

Apply polymorphism by creating a calculate function that behaves differently with two or three arguments, performing product or sum accordingly; learn function overloading, method overriding, and polymorphism in classes.

Explore object-oriented modeling of real-world systems with Python in this hands-on lab. Apply OOP concepts to design, implement, and evaluate practical solutions within a Python-based scenario.

Explore applying multiple decorators to a single function, and understand the execution order from outer to inner, using the Russian doll analogy to illustrate wrap and call flow.

Discover the three types of methods in a class—instance, class, and static—and how they operate on instance and class attributes. Learn how decorators, self, and cls determine method behavior for these attributes.

Explore how decorators support a function’s core logic by handling validation, timing, and logging, using the kitchen analogy to show nonintrusive enhancements.

Explore Python built-in exceptions, including the zero division error, and master the pdb debugger to pause, step through, and inspect code without extra print statements.

Learn to test and debug Python code using the built-in unittest framework, write assert-based tests, validate inputs like price and discount, and structure tests with TestCase classes.
