In this tutorial, we will understand about the python bytes() method and its uses.
The python bytes() method converts a given object and returns an immutable byte representation of a given object and data.
The syntax of bytes() method is
bytes(given_object, encoding,error)
If you like to use the mutable version you can try the bytearray() method.
Python bytes() Parameters
bytes() takes three optional parameters:
- given_object: The object that has to be converted.
- Encoding: String representation of the encoding method in case the given object is a string.
- error: Method to handle error in case conversion fails.
The given_object parameter can be used to initialize the byte array in the following ways:
- Integer: Returns array of size initialized to null.
- String: Return the bytes of the given string.
- Object: Just the buffer of the given object.
- Iterable: An array of iterable size will return with elements equal to iterable elements.
- No Source: Returns array with size 0.
Now let’s see some examples of the bytes() method.
Example 1: How to convert integer to string using bytes().
int_value = 4
given_object = bytes(int_value)
print(given_object)
The output will be as follow.
b‘\x00\x00\x00\x00’
Example 2: how to use bytes to convert string to bytes.
my_string = “Python Scholar”
given_object = bytes(my_string, ‘utf-8’)
print(given_object)
The output will be as follow.
b‘Python Scholar’
Example 3: How to convert iterable to bytes.
my_list = [1, 2, 3, 4, 5]
given_object = bytes(my_list)
print(given_object)
Output:
b‘\x01\x02\x03\x04\x05’
