Python bytes()

Python provides the bytes() method in order to convert provided data or objects into the byte type. The byte type may contain values from 0 to 255. Different types can be converted into the byte type using the byte() method.

bytes() Method Syntax

The bytes() method has the following syntax.

  • DATA is the string or int or list or another type that will be converted into a byte. This parameter is required.
  • ENCODING is an optional parameter that is used to specify the encoding for string type.
  • ERRORS is a rarely used optional parameter used to take action when there is an error.

Convert String To Byte

A string can be converted into a byte by using the bytes() method. Every character in the string is converted one by one. As different strings have different encodings we should provide the encoding type as a second parameter.

s = "pythontect"

a = bytes(s,'utf-8')


We can see that the output starts with the letter b which means the printed data is byte type.

Convert List To Byte

A list may contain single or more items. These items can be converted into the byte using the bytes() .

numbers = [1,2,3,4]

b = bytes(numbers)


We can see that the output of every item is converted one by one into the byte type.
