课程名称：Python和SQL应用开发：构建应用程序 概述： Python是一种广受欢迎的编程语言，由Guido van Rossum于1991年创建并发布。Python的应用广泛，可以用于服务器端构建 web 应用、与软件创建工作流、连接数据库系统、阅读和修改文件、处理大数据，以及进行复杂的数学运算。同时，Python也适用于快速原型开发及生产就绪的软件开发，并可在多个平台（如Windows、Mac、Linux、Raspberry Pi等）上运行。它的语法简单，类似英语，使得开发者可以用更少的代码行数编写程序。由于Python采用解释器系统，代码可在编写后迅速执行，从而大大加快了原型开发的速度。Python支持多种编程范式，包括过程式、面向对象和函数式编程。 SQL（结构化查询语言）是一种用于访问和操作数据库的标准语言。自1986年起，SQL成为美国国家标准协会（ANSI）和1987年国际标准化组织（ISO）的标准。SQL在数据库中可以执行查询、检索数据、插入记录、更新记录、删除记录、创建新数据库与表、以及定义存储过程和视图，同时可以设置对表、过程和视图的权限。 本课程将教你如何将关系数据库中的数据直接提取到你的Python应用中。
Python is a popular programming language. It was created by Guido van Rossum, and released in 1991.What can Python do?Python can be used on a server to create web applications.Python can be used alongside software to create workflows.Python can connect to database systems. It can also read and modify files.Python can be used to handle big data and perform complex mathematics.Python can be used for rapid prototyping, or for production-ready software development.Python works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc).Python has a simple syntax similar to the English language.Python has syntax that allows developers to write programs with fewer lines than some other programming languages.Python runs on an interpreter system, meaning that code can be executed as soon as it is written. This means that prototyping can be very quick.Python can be treated in a procedural way, an object-oriented way or a functional way.What is SQL?SQL stands for Structured Query LanguageSQL lets you access and manipulate databasesSQL became a standard of the American National Standards Institute (ANSI) in 1986, and of the International Organization for Standardization (ISO) in 1987What Can SQL do?SQL can execute queries against a databaseSQL can retrieve data from a databaseSQL can insert records in a databaseSQL can update records in a databaseSQL can delete records from a databaseSQL can create new databasesSQL can create new tables in a databaseSQL can create stored procedures in a databaseSQL can create views in a databaseSQL can set permissions on tables, procedures, and viewsYou'll learn how to pull data from relational databases straight into your Python application.
