1. What is Function in Python?

What Is Function?Challenge: Building functions Arguments Return Value Function Body Built-in Functions

2. Positional and Optional Arguments

Positional Arguments Challenge: Positional Arguments Optional Arguments Challenge: Optional Arguments

3. Arbitrary Arguments

Arbitrary Arguments Arbitrary Keyword Arguments Combination of Positional and Optional Arguments

4. Function Return Value Specification

Single Return Value Multiple Return Values None Return Value Generator Functions Challenge: Traffic lights

5. Recursion and Lambda Functions

Recursion Challenge: Pyramid Lambda Functions Immediately Invoked Lambda Expression Writing Effective and Maintainable Functions

Immediately Invoked Lambda Expression

The immediate invocation of a lambda function (IIFE) can serve several purposes:

Variable Locality: The lambda function is invoked immediately, and any variables defined within it exist only within the scope of that function. This helps avoid naming conflicts with other parts of the code;
Code Isolation: An IIFE allows you to isolate a portion of code by encapsulating it within a function. This is particularly useful when you need to define temporary variables or scopes for a specific code fragment, avoiding impact on the rest of the program;
Global Namespace Protection: Using an IIFE helps prevent additional pollution of the global namespace, as it is only used where it is declared.

square = (lambda x: x**2)(5)
print(square)

Let's break down each part of this expression:

(lambda x: x**2): This is the lambda function, created to calculate the square of a number;
(5): In this case, the lambda function is called with the argument 5.

Tarea

Edit a lambda function for converting temperature from degrees Celsius to degrees Fahrenheit. The conversion formula looks like this:

Celsius temperature is stored in the celsius_temperature variable.
The fahrenheit temperature should be saved before changing fahrenheit_temperature.
