    Python strings are immutable objects.  This has the advantage, that

    and you insist on changing string values in place instead, you may cheat
    and use MutableString.

    But the purpose of this class is an educational one: to prevent
    people from inventing their own mutable string class derived
    from UserString and than forget thereby to remove (override) the
    __hash__ method inherited from UserString.  This would lead to
    errors that would be very hard to track down.

    A faster and better solution is to rewrite your program using lists."""
