Function Exercise
Function
A function is a part of a program designed to perform a specific task and is separate from the program that calls it. In creating complex programs with many features, we are required to use functions. Functions are necessary to make it easier to read the code and to maintain it. With a function, we don’t have to write extensive code in the main program; instead, we can break it down and simply call the function within the main program. This also shortens the writing of the main program.
Functions can have parameters that are used to pass variables into a function. When declaring parameters in a function, we can also include default arguments/parameters.
Functions can also return values using the return keyword, placed within the function’s block to return the desired value back to the main program.

Simple Program in PythonPython is a high-level programming language created by Guido van Rossum. It is widely used for developing various types of programs, such as CLI programs, GUI applications (desktop), mobile applications, web applications, IoT, games, hacking programs, and more. Python is also known for being easy to learn, thanks to its clean and understandable syntax. Some features of Python include: A vast standard library; the Python distribution includes many ‘ready-to-use’...

Arithmetic OperationsArithmetic operations are a part of number processing in a computer to perform calculations. In addition to performing calculations, arithmetic operations can also be used for logical operations. The foundation of performing calculations in computer arithmetic is addition, also known as an adder. Below are the arithmetic operators in the Python programming language. Here is a simple example of an arithmetic operations program: Operator Symbol ...

Control StructureBoolean ExpressionBoolean expression is an expression that returns a value of True or False, using relational/comparison operators, as well as logical operators. Additionally, Boolean expressions can also use membership operators and identity operators in some cases. Comparison OperatorsComparison operators are operators that compare two values. These operators are also known as relational operators and are often used to create logic or conditions. Below is a list of...

Control Structure IILoop OperationsIn programming, loops function to instruct the computer to perform actions repeatedly. There are two types of loops in the Python programming language: the while loop and the for loop. The for loop is referred to as a counted loop, while the while loop is called an uncounted loop. The difference is that the for loop is typically used to repeat code a known number of times, whereas the while loop is used for iterations that depend on a condition, with an...
