Since Python 3.0, strings are stored as Unicode, i.e. each character in the string is represented by a code point. So, each string is just a sequence of Unicode code points. For efficient storage of these strings, the sequence of code points is converted into a set of bytes. The process is known as encoding. To customize the string representation of a class instance, the class needs to implement the __str__ magic method.
