Functions in Python

A function in Python is a reusable block of code that performs a specific task. Functions are defined using the def keyword, followed by the function name and parentheses ().

Here’s an example of a function definition:

In this example, greet is the function name, and name is a parameter that the function accepts. The function body consists of a single print statement that displays a greeting message.

To call or use a function, you need to provide the function name followed by parentheses (), and if the function requires any parameters, you need to pass the values for those parameters:

When the above code is executed, it will call the greet function and pass the string “Alice” as an argument. The function will then print the greeting message “Hello, Alice!”.
