Any SML coders able to translate this to Python?

We can debate what the inner function is achieving. The main point is
that functional languages create an inner function for each "let"
statement. Steve was wondering what "let" meant, and the Python code--I
hope--helped illustrate it.
Typical Scheme code is riddled with inner functions. Local variables?
An inner function. A loop? An inner function. Exception handling? An
Scheme can also be written procedurally through macros, but those macros
generate inner functions.
