Summary of some traps and tips in Python, and summary of python traps
Python is a widely used and powerful language that allows us to go deep into this language and learn some control statement skills, standard library tips, and some common traps.
Python (and its various libraries) is very large. It is used for System Automation, web applications, big data, data analysis, and security software. This document is intended to demonstrate a little-known technique that will lead you to the path of fa
the points they are targeting are different, and you can continue to follow my explanation of the adaptive model.
The theory of things may be difficult to understand, we still use an example to illustrate it:
I still like the example of that coffee: when we go to the café. I wonder if I will encounter such a problem. Originally you ordered a glass of ordinary coffe, and then his price is 10 yuan, but you tasted after a bit bitter, want to add brown s
Stencil ModeAlso called a template method pattern, a skeleton of an algorithm is defined in a method, and some steps are deferred to subclasses. The template method allows subclasses to redefine some of the steps in the algorithm without changing the attaining of the algorithm structure.Examples of our use of brewed coffee and brewing teaProcessing Flow:Coffee Brewing Method: 1. Boil the water, 2. Brew coffee
I. Definition and composition of template method patternsThe template method pattern is a very simple pattern that can be implemented simply by using Inheritance.The template method pattern consists of two parts, the first part is the abstract parent class, The second part is the concrete implementation subclass. The algorithm framework for subclasses is typically encapsulated in an abstract parent class, including implementation of some public methods and the order in which all methods in the w

(Creating a database is not difficult, but requires certain permissions and is usually done by the database administrator) you will also need to create this tutorial as an example of the table used in this database. We intend to limit the size and number of the tables to facilitate management.Suppose our database is used in a café,
Decorate model believes that we are familiar with, is a "bangoffour" in one of the most commonly used mode, the realization is quite simple. If someone is unfamiliar, take a look at the decorate model of groovy exploration, which has an example to follow in this article.
This example is a classic example of coffee in a café, coffee with original coffee, and a va

In order to pursue the sense of realism, we will be an e-commerce website, a company that buys coffee beans by mail. This website will sell several types of coffee with different quality and prices.

number of objects in the memory.
Advantages and disadvantagesThe advantage of the Meta mode is that it greatly reduces the number of objects in the memory. However, it also pays a very high price to achieve this:· The metadata-sharing mode makes the system more complex. In order for objects to be shared, some States need to be externalized, which complicate the logic of the program.· The metadata mode externalizes the state of the object, and reads the external State to slightly extend the runn

Create a table
First, we create a coffees table in our sample database, which contains the necessary information about the coffee sold in the coffee shop, including the coffee name, their prices, the number of LBS sold this week and the quantity sold so far. The coffees table will be described in detail later, as follows:
