If you use variable only once, just dont use it. Convertion to string in line 2 can be placed to line 4.
Python style guide recommends to name variables in snake case.
You can use int instead of ords.

So you will have issue in certain cases: (key=next)
You need only one call per item.
flexible_reduce is just proxy for call another function, you can remove it.
