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.
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.

If you look at the documentation for bytearray, it says: Return a new array of bytes. The bytearray type is a mutable sequence of integers in the range 0 <= x < 256.
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.
