Is there a way to quickly and easily check an object instance whether it has a property?

For example in Object API there is a has_method method that can check if the object has a named method. Is there a has_property method?

There is a get_property_list method, but I just want to quickly check existance of a property, not necessarily prepare a whole Array of Dictionaries of properties.

I found the answer. Use the in keyword.

For example to check if object1 has the text property you can do

if "text" in object1:
    # do something

The “in” keyword is not documented, I think it should be include in the documentation.

BTW looks like it was added in the 4.0 docs.

It is documented since the version 3.2 inside the class: object.
