Determine if Python variable is an instance of a built-in type

Question

I need to determine if a given Python variable is an instance of native type: str, int, float, bool, list, <

Answer 1

you can access all these types by types module:

`builtin_types = [ i for i in  types.__dict__.values() if isinstance(i, type)]`

as a reminder, import module types first

def isBuiltinTypes(var):
    return type(var) in types.__dict__.values() and not isinstance(var, types.InstanceType)
