Comparing Python Strings and Byte Objects: Reading, Talking, Learning, and Doing with Video
Byte objects in Python 2 are equivalent to str objects in Python 3, however Byte objects in Python 3 are described as ” sequence of bytes ” and are comparable to ” unicode ” objects in Python 2. Nevertheless, Byte objects and strings don’t have a lot in common. The images below illustrate a few of them:
`
-
Byte objects are sequence of
Bytes
, whereas Strings are sequence of
characters
. -
Byte objects are in
machine readable
form internally, Strings are only in
human readable
form. -
Since Byte objects are machine readable, they can be
directly stored on the disk
. Whereas, Strings
need encoding
before which they can be stored on disk.
Both String and byte objects have their own respective methods for converting to and from the other. Encoding
There are several types of encodings, such as PNG, JPG, MP3, WAV, ASCII, UTF-8, and so on. Encodings are formats used to store information digitally. Encoding is the process of transforming Strings into byte objects. This is required so that mapping may be used to save the text on disk in either ASCII or UTF-8 encoding. The encode() function accomplishes this goal. It uses encoding methods as its main justification. UTF-8 is the default encoding method.

Encryption
The technique of decoding a Byte object into a String is quite similar. The decode() function is used to achieve this. If you know the encoding that was used to encode a byte string, you can convert it back into a character string. Decoding is the opposite of encoding.
