In this step-by-step tutorial, you'll learn how to use args and kwargs in Python to add more flexibility to your functions. You'll also take a closer look at the single and double-asterisk unpacking operators, which you can use to unpack any iterable obj
In [9]: AlwaysBlueCar('green', 48392).color Out[9]: 'blue 1 2 The AlwaysBlueCar constructor simply passes on all arguments to its parent class and then overrides an internal attribute. This means if the parent class constructor changes, there’s a good chance that AlwaysBlueCar would ...
*args and **kwargs are mostly used in function definitions. *args and **kwargs allow you to pass a variable number of arguments to a function. What variable means here is that you do not know beforehand how many arguments can be passed to your function by the user so in this case yo...
It really depends on what your requirements are. The most common use case is when making function decorators (discussed in another chapter). Moreover it can be used in monkey patching as well. Monkey patching means modifying some code at runtime. Consider that you have a class with a functi...
