Bytearray ()() Function in Python

This guide covers bytearray ()() function in python with practical context and easy-to-follow details. Use it to understand the subject and apply the information confidently.

Syntax of bytearray () function:

bytearray([source[, encoding[, errors]]])

The bytearray () function returns a bytearray object which is a variable string (can be modified) of integers in the range 0 <= x <256.

If you want the immutable version use the byte () method.

Parameters of bytearray () function:

Bytearray () function has 3 parameters, all 3 are optional, yes or no.

• Source: Initialize byte array /
• Encoding: If the source is a string, you must add this parameter to convert, decode the string into bytes.
• Errors: If the source is a string, errors will provide action to retrieve when the decoding process fails.

The source parameter can be used to initialize the byte array in the following ways:

# Ví d? 1: source là chu?i 
 string1 = "tipsmake.com."

# encoding là 'utf-8'
mang1 = bytearray(string1, 'utf-8')
print(mang1) 

 # Ví d? 2: source là s?

 string2 = 10
mang2 = bytearray(string2)
print(mang2) 

 #Ví d? 3: source là list

 ListSo = [2,4,6,8,10]

mang3 = bytearray(ListSo)
print(mang3)

bytearray(b'tipsmake.com.')
bytearray(b'x00x00x00x00x00x00x00x00x00x00')
bytearray(b'x02x04x06x08n')
