对于py 文件,Python 虚拟机会先对py 文件进行编译产生PyCodeObject 对象,然后执行了co_code 字节码,即通过执行def、class 等语句创建PyFunctionObject、PyClassObject 等对象,最后得到一个从符号映射到对象的dict,自然也就是所创建的module 对象中维护的那个dict。 import 创建的module 都会被放到全局module 集合 sys.mo...

您将通过编写一个带有turn()方法的类来创建机器人,当轮到您的机器人掷骰子时,模拟器将调用该方法。类已经超出了本书的范围,所以类代码已经在myzombie.py程序中为你设置好了,它在本书的可下载 ZIP 文件中nostarch.com/automatestuff2。写方法本质上和写函数是一样的,可以使用myZombie.py程序中的turn()...
However, to understand decorators, it’s enough to think about functions as tools that turn given arguments into values.Remove ads First-Class ObjectsIn functional programming, you work almost entirely with pure functions that don’t have side effects. While not a purely functional language, ...
