Aug 23, 2023 · In Python, the bytearray() function is a powerful tool that allows you to create a mutable sequence of bytes. This function is particularly useful when you need to manipulate binary data, work with low-level data structures, or modify existing byte sequences.
- Bytearray() Function on String
- Bytearray() Function on An Integer
- Bytearray() Function on A Byte Object
- Bytearray() Function on A List of Integers
- Bytearray() Function with No Parameters
In this example, we are taking a Python Stringand performing the bytearray() function on it. The bytearray() encodes the string and converts it to byte array object in python using str.encode(). Output:
In this example, an integer is passed to the bytesrray() function, which creates an array of that size and initialized with null bytes and return byte array object in Python. Output:
In this example, we take a byte object. The read-only buffer will be used to initialize the bytes array and return the byte array object in Python. Output:
In this example, We take a Python Listof integers which is passed as a parameter to the bytearray() function. Output:
If no source is provided to the bytearray() function, an array of size 0 is created and byte array object is returned of that empty array. Output:
May 26, 2019 · Example 1: Array of bytes from an integer. When an integer is passed as an argument to the bytearray (), it creates the array of that size and initialize the array with null bytes. In the following example, we are passing the value 4 to the bytearray () function so it created the array of size 4 and initialized the elements with null bytes.
Nov 26, 2023 · In this article, let us see how to use the append and extend methods with bytearray objects with the help of some examples. ByteArray is a data structure in Python that can be used when we wish to store a collection of bytes in an ordered manner in a contiguous area of memory.
Parameter Description; source: Optional. A source to initialize the array.It can be an iterable, a buffer, a string, etc. encoding: Optional. If the source is a string, this parameter specifies the encoding used to convert the string to bytes.
A source to use when creating the bytearray object. If it is an integer, an empty bytearray object of the specified size will be created. If it is a String, make sure you specify the encoding of the source. encoding: The encoding of the string: error: Specifies what to do if the encoding fails.

Jul 14, 2020 · Python 3's bytes and bytearray classes both hold arrays of bytes, where each byte can take on a value between 0 and 255. The primary difference is that a bytes object is immutable, meaning that once created, you cannot modify its elements. By contrast, a bytearray object allows you to modify its elements.
