      In Python, you can pass a context object as a third parameter to a function. This allows you to pass additional information to the function based on its current context. Here's an example: ```python def my_function(context): # Use context information # ... pass

      Example usage:

      my_function({'name': 'Alice', 'age': 30, 'city': 'New York'}) ```

      In this example, the my_function function takes a context object as a third parameter. The context object can contain any additional information that you want to pass to the function, such as a dictionary of arguments or a value for a context variable. You can access the context object by calling its __context__ attribute, like this: python my_function().__context__

      This will return the context object as a dictionary, with any additional information you pass as values. You can then use this information in your function to access the values that you need, as shown in the example above.
