Create a dict without if

I am trying to create a function to generate dictionary but without if.
Example:

thisdict = {
  "brand": "Ford",
  "model": "Mustang",
  "year": 1964
}

But sometimes year is not available for some models and instead of using if, want to create a function with parameters: brand, model, year. Once year is None or any other attributes is None, then avoid it.

Like:

Year is None

thisdict = {
  "brand": "Ford",
  "model": "Mustang"
}

What do you think, is that possible to create without if?

>Solution :

I believe you are talking about this. you can use kwargs.

def generate_dict(**kwargs):
    return kwargs

generated_dict = generate_dict(name='John', age=30)
# {'name': 'John', 'age': 30}
