 So far, we were introduced to various types of loops, learning what structures they have and how they are applied. Now, we need to understand what an **infinite loop** is, when it occurs, and how we can **break** it using the **`break`** operator.

 Now since we know what **nested loops** are and how the **`break`** operator works, it is time to figure out how they work together. To get a better idea, we should write a **function** step by step, that should make all possible combinations of **number pairs**. The first number in the pair is increasing from 1 to 3, while the second one is decreasing from 3 to 1. Our solution must continue running until **`i + j`** **is not** equal to 2 (i.e. **`i = 1`** and **`j = 1`**).

 Up until now, we were looking at functions that execute a particular action such as printing some text, value, or a string of characters on the console. Other than such functions, there also can be functions that **return** a value as a **result** of their execution – for example, this could the multiplication of two numbers. It will be these functions that will be the topic of our discussion in the next few lines.
 
-### The return Keyword
+### The `return` Keyword
 
 To return a value that is the result of the function’s execution we use the return keyword. It must be **used in the body** of the function and indicates to the program to **stop the execution** of the function and **returns value** to the caller of the function which is written as an argument after the keyword ‘return’. In the example that follows, there is a function that reads two names from the console, concatenates them, and returns them as a result:

 After the **`return`** keyword in a given function, the execution of the function is terminated, and the execution of the program continues where the function was last called. If there are other instructions written after the **`return`** keyword, they will not be executed. Some IDEs (including **PyCharm**) will inform you of the following warning:
