若以inspect 库的两个函数为判断依据,则 Python 中的“方法与函数”具有一定的狭义性。在判断什么是函数时,它们并不把内置函数计算在内。同时,在判断什么是方法时,并非定义在类内部的都算,而是只有类方法及绑定了实例的实例方法才算是“方法”。 也许你会说,inspect 的两个判断函数并不足信,内置函数也应该算是...
id() is a built-in Python method that returns a unique id for the given object, and this id must be unique throughout the object’s lifespan.
