Python bytearray()

The bytearray() method returns an array of bytes.

Syntax

bytearray(]])

source - source to initialize the array of bytes

• string – Converts the string to bytes using str.encode()
• integer – Creates an array of provided size, all initialized to null
• iterable – Creates an array of size equal to the iterable count . Iterable integers must be between 0 <= x < 256
• Without an argument an array size will be set to 0

encoding - if the source is a string, the encoding of the string. Ex. utf-8,ascii
errors - action to take when the encoding conversion fails

Examples

byte array from string

s = "String example"

ex = bytearray(s, 'ascii')
print(ex)

Output

bytearray(b'String exapmle')

Creating byte array from integer

#integer creates array of 3
i = 3

ex = bytearray(i)
print(ex)

Output

bytearray(b'\x00\x00\x00')

Creating byte array from iterable list

list = [1,2,3]

ex = bytearray(list)
print(ex)

Output

bytearray(b'\x01\x02\x03')
