Defining Your First FunctionDefining Your First Function

In earlier examples, like those in the "Conditional Statements" section, we often assigned different values to a variable just to verify our code was functioning correctly. This method can be cumbersome, especially as our code grows more extensive. A more efficient approach involves using functions. Here's the general syntax for defining a function:

Note

All lines of code within the function's body must have consistent indentation, whether it's 2 spaces, 3, 4, or another value.

For instance, let's craft a basic function that takes in two numbers (we'll call them a and b) and returns the square of their sum.

Success! Indeed, 2 + 3 equals 5, and 5 squared is 25.

Everything was clear?
