Python 3: An interactive deep dive

In Python 3, all strings are sequences of Unicode characters. There is no such thing as a Python string encoded in `UTF-8`, or a Python string encoded as CP-1252. “Is this string `UTF-8`?” is an invalid question. `UTF-8` is a way of encoding characters as a sequence of bytes. If you want to take a string and turn it into a sequence of bytes in a particular character encoding, Python 3 can help you with that. If you want to take a sequence of bytes and turn it into a string, Python 3 can help you with that too. Bytes are not characters; bytes are bytes. Characters are an abstraction. A string is a sequence of those abstractions.
