1. What is a Function in Python?

We will consider what a function in Python and some basic techniques used to create functions is: what are the arguments of the function, what is the return value of the function, what is the body of the function, and how to use the function in the code.

What Is Function?

Challenge: Building Functions

Built-in Functions

2. Positional and Optional Arguments

Learn how to define functions in Python using positional and optional arguments. Master the flexibility of creating functions that adapt to different input scenarios.

Positional Arguments

Challenge: Positional Arguments

Optional Arguments

Challenge: Optional Arguments

3. Arbitrary Arguments

Learn to work with arbitrary arguments and keyword arguments in Python to handle variable numbers of inputs. Understand how arbitrary arguments manage flexible positional inputs and how keyword arguments organize named arguments into a dictionary for efficient function design.

Arbitrary Arguments

Arbitrary Keyword Arguments

Combination of Positional and Optional Arguments

4. Function Return Value Specification

The return value of a function is the direct result of the execution of the function, which we can use in the program. There are several types of function return values - we will consider the most commonly used.

Single Return Value

Multiple Return Values

None Return Value

Generator Functions

Challenge: Traffic lights

5. Recursion and Lambda Functions

Explore the power of recursion and lambda functions in Python. Understand how recursion allows a function to call itself for solving complex problems, and how lambda functions provide a concise way to define anonymous functions for simple tasks.

Challenge: Search Engine

Lambda Functions

Immediately Invoked Lambda Expression

Writing Effective and Maintainable Functions
