Python bytearray() Function

The python bytearray() function returns a bytearray object and can convert objects into bytearray objects, or create an empty bytearray object of the specified size.


    • bytearray(x, encoding, error)


x (optional) : It is the source that initializes the array of bytes.

encoding (optional) : It is an encoding of the string.

error (optional) : It takes action when the encoding fails.


It returns an array of bytes.

Python bytearray() Function Example 1

The below example shows an array of bytes from a string:

  • string = “Python is programming language.”# string with encoding ‘utf-8’
    arr = bytearray(string, ‘utf-8’)


  • bytearray(b’Python is programming language.’)

Explanation: In the above example, we take a variable that contains a string value and convert it into a bytearray object.

Python bytearray() Function Example 2

The below example shows an array of bytes of given integer size:

  • size = 5arr = bytearray(size)


  • bytearray(b’\x00\x00\x00\x00\x00′)

Python bytearray() Function Example 3

The below example shows an array of bytes from an iterable list:

  • rList = [2, 3, 4, 5, 6]arr = bytearray(rList)


  • bytearray(b’\x02\x03\x04\x05\x06′)

I got my training from Zeblearn in the Python Certification Training, I would like to say that say he is one of the best trainers. He has not even trained me but also motivated me to explore more and the way he executed the project, in the end, was mind-blowing.
