isinstance(obj,class_or_tuple):判断对象object是否是某种类型或元组中列出的某种类型,示例:isinstance(nums,(list,tuple,set)) issubclass(cls,class_or_tuple):判断类型cls是否是某种类型的子类或元组中列出的某个类型的子类 issubclass(True,int) 绝对值abx(x),x为数值,返回一个数的绝对值 最大值max(args1,...
函数和类是特殊的Python object。它们的类型是特殊的function类和type类。通过下面的代码可以判断一个object是否是function或者class: def is_function(obj): return type(obj) is type(lambda: None) def is_cls(obj): return type(obj) is type(int) def f(): pass class A: pass assert is_function(f)...

pythonclass 的build函数 # 如何在Python中实现类的build函数在Python中,类(Class)是面向对象编程的基本构造块,而build函数通常用于构造对象或执行对象的初始化操作。本文将引导你理解如何创建一个Python类,并实现一个可以用于初始化对象的build函数。 ## 实现流程 我们可以将实现的流程概括为以下几个步骤: | 步骤 |...
