Bytearray () function in Python

Bytearray () function in Python returns the bytearray object of a given byte array. How is the syntax of bytearray () function, what parameters does it have and how to use it?

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.

1. source: Initialize byte array /
2. encoding: If the source is a string, you must add this parameter to convert, decode the string into bytes.
3. 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 dụ 1: source là chuỗi 
 string1 = "quantrimang.com." 
 
 # encoding là 'utf-8' 
 mang1 = bytearray(string1, 'utf-8') 
 print(mang1) 
 
 # Ví dụ 2: source là số 
 
 string2 = 10 
 mang2 = bytearray(string2) 
 print(mang2) 
 
 #Ví dụ 3: source là list 
 
 ListSo = [2,4,6,8,10] 
 
 mang3 = bytearray(ListSo) 
 print(mang3) 

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