In this case, the values of b, c, and d will be set to their default values of 0. 2. Use Data Structures Another way to reduce the number of arguments passed to a function is to use data structures. Instead of passing individual arguments to a function, you can pass a single data...
Question 1: What is the purpose of default parameter values in Python functions? To enforce argument passing in the correct order. To allow a function to be called without explicitly providing all arguments. To restrict the number of arguments a function can accept. ...

Each component comes with a default search space. The search space for each parameter can be changed or set constant by passing in keyword arguments. In the following example thepenaltyparameter is held constant during the search, and thelossandalphaparameters have their search space modified from...
