Could it be that you missed the fact that strings are immutable? That
means that you can't change the content of the object once it is
initialized. In particular, it means that you e.g. have to override
__new__ instead of __init__, because the content is already fixed when
the latter is called.
Python strings rather behave like Java strings than C++ strings.
