Python bytearray: How to Use bytearray() Function

The bytearray() method returns the bytearray object, which is an array of given bytes. It gives a mutable sequence of integers in the range 0 <= x < 256.

Python bytearray Example

Python bytearray() is an inbuilt method that returns the bytearray object which is an array of the given bytes. The bytearray() function returns a bytearray object.

It can convert  objects into bytearray objects, or create an empty bytearray object of the specified size.

There are some rules followed by the bytearray() function depending on the type of source.

  1. If there is no argument is passed, an empty byte array is returned.
  2. If the source is the integer, it initializes the byte array of given length with null values.
  3. If the source is a string, encoding is mandatory and used to convert string to a byte array.
  4. If the source is iterable, such as list, it must be iterable of the integers in that range of 0 <= x < 256, which are used as initial content of the array.

See the following syntax of the bytearray() function.

Lambda, Map, Filter functions in python

Welcome to my Blog, In this article, we will learn python lambda function, Map function, and filter function.

Lambda function in python: Lambda is a one line anonymous function and lambda takes any number of arguments but can only have one expression and python lambda syntax is

Syntax: x = lambda arguments : expression

Now i will show you some python lambda function examples:

#python #anonymous function python #filter function in python #lambda #lambda python 3 #map python #python filter #python filter lambda #python lambda #python lambda examples #python map

How To Compare Tesla and Ford Company By Using Magic Methods in Python

Magic Methods are the special methods which gives us the ability to access built in syntactical features such as ‘<’, ‘>’, ‘==’, ‘+’ etc…

You must have worked with such methods without knowing them to be as magic methods. Magic methods can be identified with their names which start with __ and ends with __ like init, call, str etc. These methods are also called Dunder Methods, because of their name starting and ending with Double Underscore (Dunder).

Now there are a number of such special methods, which you might have come across too, in Python. We will just be taking an example of a few of them to understand how they work and how we can use them.

1. init

class AnyClass:
    def __init__():
        print("Init called on its own")
obj = AnyClass()

The first example is _init, _and as the name suggests, it is used for initializing objects. Init method is called on its own, ie. whenever an object is created for the class, the init method is called on its own.

The output of the above code will be given below. Note how we did not call the init method and it got invoked as we created an object for class AnyClass.

Init called on its own

2. add

Let’s move to some other example, add gives us the ability to access the built in syntax feature of the character +. Let’s see how,

class AnyClass:
    def __init__(self, var):
        self.some_var = var
    def __add__(self, other_obj):
        print("Calling the add method")
        return self.some_var + other_obj.some_var
obj1 = AnyClass(5)
obj2 = AnyClass(6)
obj1 + obj2
