In Python, class or static variables are shared across all instances of a class, unlike instance variables which are unique to each object. In this chapter, we will learn how to define class variables, understand their behavior, and see how they differ from instance variables with the help ...

In[37]:type(type)Out[37]:type 可以看出 数字1是int类型的对象 字符串abc是str类型的对象 列表、集合、字典是type类型的对象,其创建出来的对象才分别属于list、set、dict类型 函数func是function类型的对象 自定义类Foo创建出来的对象f是Foo类型,其类本身Foo则是type类型的对象。

Python staticmethod Function - Learn how to use the staticmethod function in Python to define methods that do not depend on class or instance variables.
Parse a string to receive day, month and year as three integer variables or a 3-item tuple consisting of that variable. InstantiateDateby passing those values to initialization call. This will look like: day, month, year = map(int, string_date.split('-')) ...
