The bytearray function in Python generates a bytearray object, which can either transform various objects into bytearray instances or produce an empty bytearray of a designated size.
Python bytearray Function Syntax
It has the following syntax:
Example
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.
Different Examples for Python bytearray Function
In this section, we will explore various instances of the Python bytearray function.
Python bytearray Function Example 1
The following example demonstrates how to represent a string as an array of bytes:
Example
string = "Python is programming language."
# string with encoding 'utf-8'
arr = bytearray(string, 'utf-8')
print(arr)
Output:
Output
bytearray(b'Python is programming language.')
Clarification: In the example presented above, we take a variable holding a string value and transform it into a bytearray object.
Python bytearray Function Example 2
The following example illustrates an array of bytes corresponding to a specified integer size:
Example
size = 5
arr = bytearray(size)
print(arr)
Output:
Output
bytearray(b'\x00\x00\x00\x00\x00')
Python bytearray Function Example 3
The following illustration demonstrates a byte array derived from an iterable collection:
Example
rList = [2, 3, 4, 5, 6]
arr = bytearray(rList)
print(arr)
Output:
Output
bytearray(b'\x02\x03\x04\x05\x06')
