Pythonic way to have a choice of 2-3 options as an argument to a function

Question

I have a Python function which requires a number of parameters, one of which is the type of simulation to perform. For example, the options could be \"solar\", \"view\" or \"bot

Answer 1

You can use the assert statement like this:

assert sim_types in ['solar', 'view', 'both'], 'sim type parameter must be solar, view or both'

If sim_types is not in the list, python will raise an Assertion Error
