such as UTF-8. While bytes represent raw binary data. A byte object is immutable and consists of an array of bytes (8-bit values). In Python 3, string literals are Unicode by default, while byte literals are prefixed with ab.
Converting Bytes to Strings: The .decode() Method A bytes object in Python is human-readable only when it contains readable ASCII characters. In most applications, these characters are not sufficient. We can convert a bytes object into a string using the .decode() method: data = bytes([68...
