Python的运行模式大致分为两种:一种是使用解释器(interpreter)的交互模式,另外一种是使用编辑器编写的脚本的脚本(Script)模式。使用解释器和脚本来运行Python最大的区别是前者能在你执行一行或一段代码后提供"即时反馈"让你看到是否得到了想要的结果或者告诉你代码是否有误,而后者则是将整段代码写入一个扩展名为.py的...

If you accidentally enteredmodule.cooinstead ofmodule.cppwhen you created the C++ file, Visual Studio creates the file but doesn't set the file type toC/C+ compiler. This file type is necessary to activate the presence of the C/C++ properties tab in the project properties dialog. The miside...
Classic Python (AKA CPython, often just called Python) is the most up-to-date, solid, and complete production-quality implementation of Python. It can be considered the “reference implementation” of the language. CPython is a compiler, interpreter, and set of built-in and optional extension...
If no interpreter is used, the CPython compiler generates machine code that directly runs on the CPU. Because different platforms have different instructions, the code is not cross-platform. In summary, using a compiler speeds up the process, but an interpreter makes the code cross-platform. So...
