While that matches the behavior you would see in Python, remember that Python doesn’t exactly pass by value. Let’s prove it. Python’s built-in id() returns an integer representing the memory address of the desired object. Using id(), you can verify the following assertions: Function ...

有一些属性是通用的 HTML 元素属性,或者可以应用于所有 HTML 元素,如下所示。这些属性被标识为全局属性(developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes): id class style lang HTML 元素属性,如id和class,主要用于标识或格式化单个元素或元素组。这些属性也可以由 CSS 和其他脚本语言管理。

Because Python cleans up old objects as you go (as you’ll see later), this isn’t as inefficient as it may sound: >>> S 'Spam' >>> S[0] = 'z' # Immutable objects cannot be changed ...error text omitted... TypeError: 'str' object does not support item assignment >>> S =...
... bar.append("baz")# but thislinecould be problematic, as we'll see... ... return bar 看出bug了吗?那就是在每次调用函数前没有对可变参数进行赋值,而认为该参数就是默认值。比如上面的代码,有人可能期望在反复调用foo()时返回'baz',以为每次调用foo()时,bar的值都为[],即一个空列表。
