List Of Top 3 Types Of Argument Function In Python

Function in Python is the organized and reusable block of codes. And it is useful for performing the single or the related action, and this offers better readability and reusability of the codes. If you are a newbie in the Python programming world and looking for the details about a function in Python, you are at the correct place.

Today, we are going to provide you with details about a function in Python. Moreover, we will discuss the top 3 argument types that Python users can use for improving the programs’ reusability.

 

So, let’s start with the details. But before that, let’s highlight the details about what is a function in Python and how to define it.

 

What is the function in Python?

 

It is a statement block that creates for executing the evaluative, logical, and computational tasks. Python users can use the functions to execute the repeated tasks. Python functions are also usable directly instead of writing a long code to execute a task.

 

Syntax to use a function in Python:

 

def function_name(parameters):

    “””docstring”””

    statement(s)

    return expression

 

How to define a function in Python?

 

There are certain rules that you need to follow for defining the function in Python. And these are:

 

• The function code should start with the def keyword and then be followed by the name of the function, parentheses(), and finally with a colon(:).
• The thing that is within the parentheses is the parameter or the input of the given function. (The values defined in the function are known as arguments).
• Once the function gets declared, you can easily write a description with the help of docstring (“”” “””).
• Finally, you need to use print or the return statement to get the output.

 

The syntax for defining a function in Python:

 

1. def FunctionName(input or parameter):
2. “”” Test function “””
3. # code to do the computation to the parameter
4. print(output)
5. return output

 

Key Points   What are the types of functions in Python?   A function in Python can be of two different types:   ●      User-defined: It is declared by the Python user for executing the basic function. ●      Built-in: Python consists of various pre-defined functions. Those are known as built-in Python functions.

 

How can Python users call the particular function within the present program?

 

A particular function can easily call using the name of the function. You just require the use of the necessary values to the parameters while you define the function in your program.

 

How you can call a function:

 

functionName(argument)

 

Here, we are using two numbers that we have added and get the output using the print function and return statement.

 

Example of calling a function with the print & return statement

The output will be:

 

The sum is: 20

 

NOTE: In this given example, a and b are parameters; on the other hand, 5 and 15 are taken as the functions’ arguments.

 

List of top 3 argument types in Python

 

First, check what the argument is?

 

It is the value that is being passed in the function’s parenthesis. These functions use a variety of arguments that are separated with the comma(,).

 

The top 3 argument types that Python users can use are:

 

• Variable-length arguments

 

Python users can easily pass the argument’s variable number to the specific function with the help of using particular symbols. And those are:

 

• Keyword Arguments – **kwargs
• Non-Keyword Arguments – *args

 

This is how you can use this argument:

Output:

 

first == Code

last == Avail

 

• Keyword arguments

 

It allows the callers to declare the argument name with a particular value. It always supports the caller not to memorize the parameters’ order. This is how you can use this argument:

Output:

 

Code Avail

Code Avail

 

• Default arguments

 

It is the default value. And it is used only if the value may not be in the named function. This is how you can use it:

Output:

 

x: 15

y: 35

 

Let’s conclude it!

 

There is a situation when you need to enhance the reusability and the readability of your codes. In that case, using the function in Python is always a good idea. To make your work easier, we have used the arguments within the Python function. It means you must know the top 3 arguments that are being used in the Python programs.

 

We have discussed all those arguments with suitable examples in the above section. We also have detailed how you can define and call the necessary function into your program. If you want to know about these, connect with the Python experts.
