You can also use it to subtract two numbers: Python >>> -273.15 -273.15 >>> 5 - 2 3 In this code snippet, the minus sign (-) in the first example is a unary operator, and the number 273.15 is the operand. In the second example, the same symbol is a binary operator, and ...
%%add_method_toDeckdefput_card(self,card):self.cards.append(card) 作为示例,我们可以把刚刚弹出的牌放回去。 deck.put_card(card)len(deck.cards)52 要洗牌,我们可以使用random模块中的shuffle函数: importrandom%%add_method_toDeckdefshuffle(self):random.shuffle(self.cards) 如果我们洗牌并打印前几张卡片...
在真正的Python bytecode中,大概有一半的指令有参数。像我们的例子一样,参数和指令打包在一起。注意指令的参数和传递给对应方法的参数是不同的。 第二,指令ADD_TWO_VALUES不需要任何参数,它从解释器栈中弹出所需的值。这正是以栈为基础的解释器的特点。 记得我们说过只要给出合适的指令集,不需要对解释器做任何...
这个练习目前还没有问题,但你可以通过 help@learncodethehardway.org 向我提问以获取帮助。也许你的问题会出现在这里。 练习20:函数和文件 记住函数的清单,然后在这个练习中要特别注意函数和文件如何一起工作以制作有用的东西。你还应该继续在运行代码之前只输入几行。如果发现自己输入了太多行,请删除它们然后重新输...
这个方法就是run_code,它将前面定义的what_to_execute字典作为一个参数。循环所有的指令,处理传给指令的参数,并且在解释器对象里调用对应的方法。 defrun_code(self, what_to_execute): instructions = what_to_execute["instructions"] numbers = what_to_execute["numbers"]foreach_stepininstructions: ...
Increment (+=x) Adds x to the operand. Decrement (-=x) Subtracts x from the operand. Flood division (//) A division operand that always returns an integer. Exponent (**) Exponential calculation of operators. The sample code below demonstrates how to use them: PythonCopy Code def Python...

This package also has an extensive knowledge of Python bytecode magic numbers, including PyPy and others, and how to translate fromsys.sys_infomajor, minor, and release numbers to the corresponding magic value. So if you want to write a cross-version assembler, bytecode-level analyzer, or op...
