What exactly happens when a method is called? You may have noticed that
x.f() was called without an argument above, even though the function
definition for f specified an argument. What happened to the argument?
Surely Python raises an exception when a function that requires an
argument is called without any -- even if the argument isn't actually
used...
Actually, you may have guessed the answer: the special thing about
methods is that the object is passed as the first argument of the
function. In our example, the call x.f() is exactly equivalent to
MyClass.f(x). In general, calling a method with a list of n arguments is
equivalent to calling the corresponding function with an argument list
that is created by inserting the method's object before the first argument.
