class T: def __init__(self, x, y): print('Initializing T', x, y) self.x = x self.y = y 把这两件事放在一起看,有没有联想到什么?没错,在这个例子里__dict__中读取到的值就是在构造过程 __init__ 中赋的值。 不仅如此,我们再看看如果类之间存在继承关系,会发生什么,例如下面的例子 cl...

This blocking function will start a process and wait until the new process exits before moving on. The documentation recommends using run() for all cases that it can handle. For edge cases where you need more control, the Popen class can be used. Popen is the underlying class for the ...
