Nothing really. I went with a variation of the suggested work around...
it's just that with Python I don't normally have to use work arounds and
normally one obvious approach is correct:

That's what a multimap is.
iirc, a C++ multimap provides a flat view of the data, so you need to
provide custom enumeration and iteration methods as well.

It counts both keys individually as separate keys. The Python workaround
does not... see examples... notice the key(s) that are '4'
Python output (using the k = [] idea):
Key: 4 Value: [[13, 'Visa'],

Same key, but different values. No overwrites either They all must
be inserted into the container

Recently had a need to us a multimap container in C++. I now need to
