python correct way to call a function

Functions are a fundamental building block in Python programming. They allow you to encapsulate a piece of code and reuse it throughout your program, promoting modularity and readability. In this tutorial, we'll explore the correct way to call a function in Python, covering best practices and providing code examples.
Let's start by defining a simple function. Consider the following example:
Here, we've defined a function called greet that takes a single parameter name and prints a greeting.
To call the function, you need to provide the required arguments. In this case, the greet function expects a single argument, which is the name. Here's how you call the function:
This will output:
Functions can also return values. When calling a function that returns a value, it's essential to capture and use that value. Consider the following example:
In this example, the add_numbers function takes two parameters, adds them, and returns the result. The returned value is then assigned to the variable result and printed.
Python allows you to specify arguments by name using keyword arguments. This can enhance code readability, especially when dealing with functions with multiple parameters. Example:
You can set default values for function parameters, making them optional when calling the function. Here's an example:
In this tutorial, we've covered the basics of calling functions in Python, including passing arguments, handling return values, using keyword arguments, and setting default values. Following these best practices will help you write clean, modular, and readable Python code.
