follows:E:\python2.7.11\python.exe e:/py_prj/python_cookbook/chapter5.pyCall Decorator_tryCall ExampleWrapperThe result of example.__name__ here is wrapper, not example. That is, the properties of the modified function have changed. Because the adorner can be equivalent to write Example=decorator_try (example). The return value of Decorator_try is wrapper. So the example attribute is then changed to wrapper. To eliminate this effect, we need to use wraps.After modifying the wrapper with wraps,

1. The default parameters of the function must be immutableIf the default parameter of a function is a mutable object, then the default parameter is modified outside the function and affects the function itself.def spam (A, b=None): # B to be an immutable parameter, you cannot use a variable parameter such as an empty list [] ... if is None: ... = []...2. Anonymous functions1. You can use anonymous functions when you can't think of a function name or want a short operationLambda

), which provides CLI programs with a virtual machine environment that uploads and runs managed code on a variety of possible platforms, is just a specification, for example, Microsoft and Momo have their own implementations. The JIT and GC of the CLR for net should fall into this scope.The. NET Framework is a Microsoft implementation of the CLI, and, of course, the best implementation of the present, the. NET Framework mainly includes the CLR and the BCL,CLR is the core of the implementation of

operation time complexity is O (log N), where n is the size of the heap, so even when N is very large, they are still running fast. In the above code, the queue contains a tuple (-priority, index, item). The goal of a negative priority is to make the element sort from highest to lowest priority. This sort of heap is the opposite of regular sort by priority from low to high. The role of the index variable is to ensure that the same priority elements are sorted correctly. By saving an ever-increa

1. Traversing a stringThere is no iterative operation in SQL, so you can implement this process by connecting a table that is used as a traversal pointer.1 Selectsubstr (E.ename, Iter.pos,1) asC2 from(SelectEname fromEmpwhereEname= 'KING') E,3(SelectId asPos fromT10) ITER4 whereIter.posLength (e.ename);There are 10 data in T10, ID from 1-10.The FROM clause provides a Cartesian product, and the resulting table resemblesThe WHERE clause restricts the POS range. SQL

Although it is convenient and easy to use, I personally think its UI performance is not too brilliant. Today I accidentally saw jquery tools-a jquery-based UI presentation framework, its UI function is similar to (or imitated) flex. This framework provides tabs (Tab/TAB) overlay (overlay), tooltip (prompt box), scrollable (scroll Information bar), expose (highlighted), and flahembed (video playback embedded) six Main functions (called the six tools on

It is necessary to make a simple tabs plug-in. Before designing the plug-in, sort out the ideas and implement the main functions such as tabs, automatic rotation, and ajax, and then arrange the dom, the traditional tabs is one of the most widely used Web pages. There are also many jquery plug-ins and non-jquery plug-ins. Some friends asked me how to use jquery. u
