What can go inside the model parenthesis?

dict works
json too
another model?

import fhirclient.models.questionnaire as Q
import fhirclient.models.coding as C

e.g    valuecoding = C.Coding({'code':'code', 'system': 'system':'display': 'display'} )
option = Q.QuestionnaireItemOption({valuecoding})

I'm no python expert, but I would do this:

option = Q.QuestionnaireItemOption()
option.valueCoding = valuecoding

help(option) says

 |  __init__(self, jsondict=None, strict=True)
 |      Initialize all valid properties.
 |
 |      :raises: FHIRValidationError on validation errors, unless strict is False
 |      :param dict jsondict: A JSON dictionary to use for initialization
 |      :param bool strict: If True (the default), invalid variables will raise a TypeError

So it looks like you can put in a jsondict in the parens.
Tried this and it also seems to work:

option = Q.QuestionnaireItemOption({'valueCoding':valuecoding.as_json()})
print(json.dumps(option.as_json(), indent=4))

{
    "valueCoding": {
        "code": "code",
        "display": "display",
        "system": "system"
    }
}

It's designed to take an in-memory representation of FHIR-JSON (meaning technically it's a Python dict).
