In Python, a function is a well-organized and reusable code block. It's also handy for completing a single or related activity, and it improves the programs' readability and reusability. If you're new to Python programming and want to learn more about a specific function, you've come to the right place.
Today, we'll go through the details of a function in Python. We'll also go through the top three argument types that Python programmers can use to make their codes reusable.
So, let's get down to the section below. But first, let's go through the basics of what a function in Python is and how to define one.
What is the Python function?
It's a statement block used to carry out evaluative, logical, and computational operations. Python users can use the functions to perform repetitive operations. Instead of creating a long code to complete a task, Python functions can be used immediately.
Syntax to use a function in Python:
def function_name(parameters):
"""docstring"""
statement(s)
return expression
In Python, how do you define a function?
When defining a function in Python, there are several guidelines to follow. These are the following:
The function code should begin with the def keyword, followed by the function's name, parentheses(), and finally, a colon (:).
The parameter of the supplied function is included within the parentheses.
With the help of docstring, you can quickly describe the function once it has been declared (""" """).
Finally, to receive the output, you must use print or the return statement.
Why do we utilize a function in Python?
You can improve the readability of your Python code and its reusability with the aid of the functions. It means that instead of creating a long code, you may use the functions.
The debugging procedure is made much easier due to the programs' simplicity. You can also easily obtain errors. As a result, making use of the function is an excellent idea.
Python's top three argument types are listed below.
Check first to see what the argument is.
In the function's parenthesis, it's the value that's being supplied. These functions take a number of parameters, which are separated by commas (,).
Python users can utilize the following three sorts of arguments:
Variable-length arguments
With the use of certain symbols, Python users may quickly transmit the argument's variable number to the relevant function. These are the ones:
With the use of certain symbols, Python users may quickly give the argument's variable number to the relevant function. These are the ones:
**kwargs - Keyword Arguments
*args - Arguments that aren't keywords
This is how you can put this argument to work for you:
Output:
first == Code
last == Avail
Arguments by default
It's the default setting. It's only utilized if the value isn't found in the designated function. Here's how you can put it to use:
Output:
x: 15
y: 35
Keywords Arguments
It lets callers express a specific value for the parameter name. It always encourages the caller not to memorize the sequence of the parameters. This is how you can put this argument to work for you:
Output:
Code Avail
Code Avail
Let’s wrap it up!
There are times when you'll want to improve the reusability and your code's readability. It's usually a good idea to use the function in Python in this scenario. The parameters within the Python function have been utilized to make your task simpler. It implies that you should be familiar with the top three parameters used in the Python program.
In the previous section, we addressed all of these points with appropriate examples. We've also gone through how to define it in detail. Connect with Python professionals if you want to learn more about them.
