depending on the size needed to hold a pointer when it has been cast to an integer type. A NULL pointer will always be returned as the Python integer 0. When packing pointer-sized values, Python integer or long integer objects may be used. For example, the Alpha and Merced processors ...
属性引用使用和Python中所有的属性引用一样的标准语法:obj.name。类对象创建后,类命名空间中所有的命名都是有效属性名。所以如果类定义是这样: class MyClass: "A simple example class" i = 12345 def f(self): return 'hello world' 1. 2. 3. 4. 5. 那么MyClass.i和MyClass.f是有效的属性引用,分别...
and there is also theStructclass (new in Python 2.5). Format specifiers are converted from their string format to a compiled representation, similar to the way regular expressions are. The conversion takes some resources, so it is typically more efficient to do it once when creating aStructinst...

0. When packing pointer-sized values, Python integer or long integer objects may be used. For example, the Alpha and Merced processors use 64-bit pointer values, meaning a Python long integer will be used to hold the pointer; other platforms use 32-bit pointers and will use a Python ...

#自动化测试和python群组:http://groups.google.com/group/automation_testing_python #参考资料:《The PythonStandard Libraryby Example 2011》 实现字节数据和python数据类型的转换。格式指示器会有类似于re模块一样的变异机制。所以创建Struct实例,再调用实例方法会比使用模块函数更加有效。
