The way you did, actually :).
Look for "It's better to ask for forgiveness than for permission" (or
so) and the term "duck typing". That's the way to do it in python.
And just for completeness' sake: You could have also checked for actual
types via "isinstance(your_variable, dict) or "type(your_variable) is
type(dict)" or ... But your approach is the recomended one.
