The idea of such types of arguments is to allow a user to specify the argument names along with the values so that there is no need to remember the order of the arguments. Here is an example of the same: # Python program to demonstrate Keyword Arguments def student(firstname, lastname)...

Return whether an object is an instance of a class or of a subclass thereof. With a type as second argument, return whether that is the object's type. The form using a tuple, isinstance(x, (A, B, ...)), is a shortcut for ...

other-cls-instance --> |instance-of|other-cls; 1. 2. 3. 4. 5. 6. 7. type有两种调用方式,一种是最常用的接受一个对象参数,返回该对象的类型,另一种是不怎么常用的,直接创建一个新的类型。 # usage with one argument type(object) # 返回对象的类型,这里返回的是 `type` ...
