What Is The Most Efficient Method To Convert A String To Bytes In Python 3?

In Python 3, you can convert a string to bytes using the bytes() built-in function. Here are a few examples:

  1. Convert a string to bytes using the default UTF-8 encoding:
my_string = "This is a string"
my_bytes = bytes(my_string, 'utf-8')
  1. Convert a string to bytes using a different encoding, such as ASCII or UTF-16:
my_string = "This is a string"
my_bytes = bytes(my_string, 'ascii')
my_string = "This is a string"
my_bytes = bytes(my_string, 'utf-16')
  1. Convert a string to bytes using the default encoding of your operating system:
import locale

my_string = "This is a string"
encoding = locale.getpreferredencoding()
my_bytes = bytes(my_string, encoding)

Note: bytes() returns an immutable bytes object. If you need a mutable byte array, you can use the bytearray() built-in function in a similar way.
