问题 Are calling method and called method both same? What I would like to know is "calling method" means the method which calls another method that is main method in most cases, or the main method itself? 回答1: The calling method is the method that contains the actual call; the called method is the method being called. They are different. For example: // Calling method void f() { g(); } // Called method void g() { } 回答2: The calling method is the method that contains the actual call. The called

问题 Using Django ~=1.11 and Python 3.6 I need to store 'calculated' variables as fields in the Django model database. Here's a model: from django.db import models from datetime import date class Person(model.Model) "Last Name" last_name = models.CharField(max_length=25) "Birthday" birth_date = models.DateField() "City of birth" city_of_birth = models.CharField(max_length=25) I am creating a Unique ID using these fields. Specifically, I'm conjoining parts of each field into one string variable

Python Wrap Class Method

问题 I'm trying to create an object with a run method that will be wrapped by a _wrap_run method . I'd like to be able to call the method and it's wrapper by simply typing instance.run() and I'd like to be able to subclass the object so I can override the run() method and have it still execute the wrapper. More simply put, I want people to be able to subclass A and override run() but still have calls to the run() method execute the wrapper function. I'm having some difficulty with the mechanics of

问题 Hi I am trying to implement a method that will take a method (any method in the grand scheme of things) as a parameter. I want this parameter method to run when in the method that called it only, If the method that passes into this method has a return value then it should still be able to return its value. I want to measure the performance of the methods that are passed in. return Performance(GetNextPage(eEvent, false)); public static T Performance<T>(T method) { T toReturn; Stopwatch sw =

问题 I was able to create this dynamic elements. My purpose in this is to create dynamic divs that will be based on "count", and inside that div, I can add multiple textboxes. Here's what I came up with You'll notice that the first click, it will not be the expected result. But when you click it the 2nd time, it will work. I should be missing something.

Ruby what class gets a method when there is no explicit receiver?

问题 random question here. I'm not sure if there's a term for this, but I'm wondering when you define a method without an explicit receiver, how can you know what class gets the method? Is it whatever self is in that context? self in the context of a class definition is the class being defined, and methods defined with an implicit receiver are bound to the class, which we see all the time. But, if I define a method inside an instance method, that 'sub_method' is getting put on the outer class as
