Python bytes()

bytes() returns an immutable bytes object, made up of a sequence of integers in the range 0 <=x < 256.

The returned bytes sequence is immutable. A mutable bytes sequence can be used instead by calling is bytearry() .

Syntax

bytes(]])

bytes() takes three optional parameters:

  • source – initialize the array of bytes. Can be String or Integer
  • encoding  – if the source is a string, the encoding of the string
  • errors  – the action to take when the encoding conversion fails

Example

Creating empty array of bytes

x = bytes(3)
print(x)

Output

b'\x00\x00\x00'

Introducing a String

str = "CodeIt"

# encoding 'utf-8'
ex1= bytes(str, 'utf-8')

#encdoing 'utf-16'
ex2= bytes(str, 'utf-16')

print(ex1)
print(ex2)

Output

b'CodeIt'
b'\xff\xfeC\x00o\x00d\x00e\x00I\x00t\x00'
