How to determine type of nested data structures in Python?

Question

I am currently translating some Python to F#, specifically neural-networks-and-deep-learning .

To make sure the data structures are correctly translated the details o

As I commented, this is impossible in Python, because lists are untyped.

You can still pretend to do it:

def typ(something, depth=0):
    if depth > 63:
        return "..."
    if type(something) == tuple:
        return ">"
    elif type(something) == list:
        return ""
    else:
        return str(type(something))

That returns the string >>,>>> for your example.

edit: To make it look more like F# you could do this instead:

def typ(something, depth=0):
    if depth > 63:
        return "..."
    if type(something) == tuple:
        return " * ".join(typ(ding, depth+1) for ding in something)
    elif type(something) == list:
        return (typ(something[0]) if something else 'empty') + " []"
    else:
        return str(type(something, depth+1)).split("'")[1]

which will return int [] [] * str [] in your example.
