882>Python has a more general concept of callable object, that is every object that can be called, which means applied on some data.
我在读一篇博客的时候看到这句话，作者认为Python对callable的概念是比较宽泛的，任何对象都可以被调用。这样说对么？如何理解？
Python的内建的callable()函数可以用来检测是否能够调用，如果所有对象都可以call，那么为什么还有检测呢？

仔细一看，这是英语断句的问题啊
不是“每个对象都能被调用”，而是“callable object”是“所有能被调用的对象”，最后那个从句解释调用的概念是“被应用于数据”。
