Course Overview
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.
Signature
-
- bytearray(x, encoding, error)
Parameters
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.
Return
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’)
print(arr)
Output:
- 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)
print(arr)
Output:
- 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)
print(arr)
Output:
- bytearray(b’\x02\x03\x04\x05\x06′)
