Python bytearray
Python bytearray() method returns an array of bytes of the given size and initialization values. In other words the Python bytearray() function returns a bytearray object. It can convert Python objects into Python bytearray objects, or create empty bytearray object of the specified size.
Syntax of bytearray Method
bytearray([source[, encoding[, errors]]])
All the parameters in bytearray method are optional.
Parameters of bytearray Method
- source : Source to initialize the array of bytes. This is optional parameter.
- encoding : If the source is a string, the encoding of the string. The encoding parameter also optional parameter.
- errors : If the source is a string, the action to take when the encoding conversion fails. This is also optional parameter.
What is a bytearray in Python ?

How to Use source Parameter of bytearray in Python ?
The source parameter can be used to initialize the byte array.
How to Use source Parameter of bytearray in Python
| Data Type | Description |
|---|---|
| String | Converts the string to bytes using str.encode() Must also provide encoding and optionally errors |
| Integer | Creates an array of provided size, all initialized to null |
| Object | A read-only buffer of the object will be used to initialize the byte array |
| Iterable | Creates an array of size equal to the iterable count and initialized to the iterable elements Must be iterable of integers between 0 <= x < 256 |
| No source (arguments) | If no arguments given in bytearray() method it creates an array of size 0. |
