The c object is paired with the self parameter of the class definition. The number 5 is paired with the radius parameter. $ ./methods.py 5 78.5398 In Python, we can call methods in two ways. There are bounded and unbounded method calls. ...
In Python, classes are objects (values), handled like other objects. Thus, you can pass a class as an argument in a call to a function. Similarly, a function can return a class as the result of a call. A class, just like any other object, can be bound to a variable (local or ...
