Both values are passed during the function call. Hence, these values are used instead of the default values. 2. add_number(2) Only one value is passed during the function call. So, according to the positional argument2is assigned to argumenta, and the default value is used for parameterb...
In the example above, I generated a new string based on the input values of two already-created variables by using thecurly brackets placeholderto show where the variables should be written. Then, I passed the variables as a parameter to the format method. On the other hand, we might want...

The HTTP trigger is defined as a method that takes a named binding parameter, which is an HttpRequest object, and returns an HttpResponse object. You apply the function_name decorator to the method to define the function name, while the HTTP endpoint is set by applying the route decorator....

As you see, this class decorator follows the same template as your function decorators. The only difference is that you’re using cls instead of func as the parameter name to indicate that it’s meant to be a class decorator. Check it out in practice: Python >>> from decorators import...
