how to think like computer scientist learning with python

this case, the modification is visible to the caller, and the function that works is called the modifier.17th Chapter Classes and methods1. For a function written inside a class, we call it a method.When we invoke a method, it is possible to use the principal and method names directly, for example (Xiaoming is a principal, and H1 is a method name):class Hello (object): def H1 (): Print ' Hello, world!. ' = Hello () xiaoming.h1 ()In a method, a principal is assigned to the first par

the C language because they are two different objects in C, as in the following example:>>> a = [111, 222, 333]>>> b = aprint a[444, 222, 333]9. List parameters:When we pass a list as a parameter into a function, the function gets a reference to the list. Therefore, in the function to modify the list, the function is also affected outside;This chapter gives special attention to the fact that the assignment of a list is a reference to the original list. To change the list or create a new list;1
