Function Arguments Python Example -

In programming, a parameter is a variable in a function or method declaration.📅 tue, may 7, 2024 ⏲️ ~ 5 minutes beginner.

Most of the time you will see people use the args keyword but args is not the reserved keyword in python, we can use any name instead of args but use the asterisk(*) as a prefix.Input, if any, is defined for a function using parameters.A function in python is defined using a def keyword followed by the name of the function, then followed by a set of round parentheses.

As nums is a python dictionary, you can call the items() method on the dict object to get a list of tuples.My_sum() takes all the parameters that are provided in the input and packs them all into a single iterable object named args.

Then the body is written by indenting by 4 spaces or a tab.Parameters in python are the variables that take the values passed as arguments when calling the functions.When the function is called, we pass along a first name, which is used inside.

The * and ** operators serve different purposes in each of those situations.Whereby argument passing is by default based a positional basis (1st argument, 2nd argument etc.), python will let you name the arguments and pass them in any order.

In this example, you're no longer passing a list to my_sum().instead, you're passing three different positional arguments.Result = add_numbers ( 3, 5) in this example, the `add_numbers` function takes two positional arguments, `a` and `b`.Learn how to leverage *args and **kwargs to handle variable numbers of arguments in your functions, enabling greater flexibility and efficiency in your python code.

Explore different types of function arguments for efficie.Default parameters are added by simply using an equals sign after the argument name.

Add_number(2, 3) both values are passed during the function call.So to solve this problem we have a provision in python to use an asterisk(*) symbol before the parameter name in the function, for example, *args.
