With that said, you use the standard method of mutating your inputs/outputs to the expected types.

These User Actors of mine can be quite useful for that: https://troikatronix.com/add-ons/mutator-user-actors/

Copy this. 

Thank you for this information. I appreciate it. :)

Pythoner basically passes values from Isadora into your Python script as raw Python objects. There is:
❌ No built-in type system for inputs/outputs
❌ No way to declare types like “this input is always an int” at the actor level
✅ Only positional passing of values

With that said, you use the standard method of mutating your inputs/outputs to the expected types. 

Additionally in your python code it is useful to test the type of inputs to ensure proper function. (I honestly don't do this often because I'm quite careful with my input connections. Using user actors to contain my pythoner scripts makes this even easier because you can set the type of the user inputs before attaching them).

You might look into using:

# Validate types
if not isinstance(my_input, expected_type):
    # convert or handle error

# Convert if needed
my_input = int(my_input)  # or float, list, etc.

This allows you to test incoming values in your python_init() function
