...method. The built-in staticmethod() wraps its function argument in a special kind of descriptor whose __get__() method returns the original function unchanged. More on __get__ methods: in Python 2.2, the magic of binding methods to instances (even for classic classes!) is done through the __get__ method of the object found in the class. The __get__ method for regular function objects returns a bound method object; the __get__ method for staticmethod objects returns the underlying fu...

...method, x+1 causes a call to x.__add__(1). The method implementation will have to analyze the other argument's type in order to be able to implement the operation correctly. If the method implementation decides that it doesn't know how to implement the operation for this particular combination of argument types, it should return the special singleton value NotImplemented. (This behavior is the same as for classic classes lacking a __coerce__ method; the difference is that the __coerce__ metho...
...method1(10) is equivalent to method1(aninstance, 10). In the example if this call, first a temporary BoundMethod instance is created with the following constructor call: temp = BoundMethod(method1, aninstance); then this instance is called as temp(10). After the call, the temporary instance is discarded. The __init__ method is invoked for the constructor call BoundMethod(method1, aninstance). It simply saves away its arguments. The __call__ method is invoked when the bound...
...definition file. Like YACC, YAPPS supports custom code before and after the grammar definition. YAPPS parsers integrate with the scanner through a Scanner object, which is passed to the parser as a constructor argument. Even though YAPPS supports definition of tokens in the grammar, we have not used this capability in XPath, since we have provided my own scanner class. The YAPPS parser will only require a token() method from the scanner object, which must return a four-tuple (start, e...

...methods derived by D override methods derived by A, but in Z, which still is a subclass of K3, methods derived by A override methods derived by D! This is a violation of monotonicity. Moreover, the Python 2.2 linearization of Z is also inconsistent with local precedence ordering, since the local precedence list of the class Z is [K1, K2, K3] (K2 precedes K3), whereas in the linearization of Z K2 follows K3. These problems explain why the 2.2 rule has been dismissed in favor of the C3 rule. ...

...method, 'sendall()'. This method is guaranteed to send all data - this is not guaranteed by the 'send()' method. See also SF patch #474307. The standard library has been updated to use this method where appropriate. Many bugs were fixed. The following is a list of some of the major or notable fixes: Fix for incorrectly swapped arguments to PyFrame_BlockSetup in ceval.c. This bug could cause python to crash. It was related to using a 'continue' inside a 'try' block. SF bug #422004: Py_Initialis...
...methods now accept an optional argument specifying a fill character other than a space. When method objects have an attribute that can be satisfied either by the function object or by the method object, the function object's attribute usually wins. Christian Tismer pointed out that that this is really a mistake, because this only happens for special methods (like __reduce__) where the method object's version is really more appropriate than the function's attribute. So from now on, all method a...
