Python的copy模块中的copy()method 其实是与deep copy相对的shallow copy。copy.copy(object)就等于是对 object 做了shallow copy。 先说结论: 对于简单的 object,用shallow copy和deep copy没区别: >>>importcopy>>> origin = 1 >>> cop1 =copy.copy(origin)#cop1 是 origin 的shallow copy>>> cop2 =...
Shallow copy operation on arbitrary Python objects. deepcopy(x, memo=None, _nil=[]) Deep copy operation on arbitrary Python objects.This version does not copy types like module, class, function, method, nor stack trace, stack frame, nor file, socket, window, nor array, nor any similar ty...

class B: def __init__(self,a): self.a=a def __len__(self): print('this is magic method len') return 2>>>a=B(1)>>>print(len(a))this is magic method len2可以看到,魔术方法在类或对象的某些事件出发后会自动执行,如果希望根据自己的程序定制特殊功能的类,那么就需要对这些方法进行重写...
在Python中,函数(function)和方法(method)是两个类似但不同的概念。函数是独立的代码块,可以通过名称调用并执行,而方法是与对象关联的函数。区分它们的一个重要标志是方法必须通过一个对象来调用,而函数则没有这个限制。 # 示例1:函数 def greet(): print("Hello!") greet() # 调用函数 # 示例2:方法 class...
