Python关于mySQL的连接插件众多,Bottle下也有人专门开发的插件:bottle-mysql具体使用方法见官方,总共感觉其用法限制太多,其使用起来不方便,最适合的当然是,mySQL官网给Python提供的通用官方驱动,用起来很顺手:mysql-connector 具体操作如下:
# -*- coding: utf-8 -*- #!/usr/bin/python # filename: login_admin.py # codedtime: 2014-9-7 11:26:11 import bottle import mysql.connector # 导入mysql数据库连接器 def check_userinfo(): a_list = [] # 创建一个空列表 username = bottle.request.GET.get('loginname','').strip() # 用户名 password = bottle.request.GET.get('password','').strip() # 密码 if username is not None or password is not None: try: # 连接数据库 conn = mysql.connector.connect(user='root', password='123456', database='myblog') cursor = conn.cursor() # 创建数据游标 # 执行查询 query = ("SELECT username, password FROM mb_users " "WHERE username=%s and password=%s") cursor.execute(query, (username, password)) a_list = cursor.fetchall() # fetchone获取一个元组 #count = int(cursor.rowcount) # 获取元组个数 return a_list except mysql.connector.Error as err: print("Something went wrong: {}".format(err)) exit() finally: conn.commit() # 提交修改 cursor.close() # 关闭数据库 conn.close() else: return a_list def login_admin(): if bottle.request.GET.get('bs-submit','').strip(): #点击登录按钮 a_list = check_userinfo() if a_list: a_name = a_list[0][0] # 获得用户名 return bottle.template('templates/index_user.tpl', username = a_name) else: return bottle.template('templates/login_admin.tpl', action='/login_admin', error_info='请输入正确的用户名或密码!') else: return bottle.template('templates/login_admin.tpl', action='', error_info=' ')
以上是MySQL在Botlle中的简单用法,
顺便提一下:安装和管理mySQL,建议安装使用XAMPP,XAMPP集成了Apache, MySQL、PHP、Tomcat等多种工具,一次性解决安装,不用自己繁琐的一个个安装和配置,而且管理也很方便。XAMPP安装的MySQL默认用户是:root 密码为空。

Python's flexibility is reflected in multi-paradigm support and dynamic type systems, while ease of use comes from a simple syntax and rich standard library. 1. Flexibility: Supports object-oriented, functional and procedural programming, and dynamic type systems improve development efficiency. 2. Ease of use: The grammar is close to natural language, the standard library covers a wide range of functions, and simplifies the development process.

Python is highly favored for its simplicity and power, suitable for all needs from beginners to advanced developers. Its versatility is reflected in: 1) Easy to learn and use, simple syntax; 2) Rich libraries and frameworks, such as NumPy, Pandas, etc.; 3) Cross-platform support, which can be run on a variety of operating systems; 4) Suitable for scripting and automation tasks to improve work efficiency.

Yes, learn Python in two hours a day. 1. Develop a reasonable study plan, 2. Select the right learning resources, 3. Consolidate the knowledge learned through practice. These steps can help you master Python in a short time.

Python is suitable for rapid development and data processing, while C is suitable for high performance and underlying control. 1) Python is easy to use, with concise syntax, and is suitable for data science and web development. 2) C has high performance and accurate control, and is often used in gaming and system programming.

The time required to learn Python varies from person to person, mainly influenced by previous programming experience, learning motivation, learning resources and methods, and learning rhythm. Set realistic learning goals and learn best through practical projects.

Python excels in automation, scripting, and task management. 1) Automation: File backup is realized through standard libraries such as os and shutil. 2) Script writing: Use the psutil library to monitor system resources. 3) Task management: Use the schedule library to schedule tasks. Python's ease of use and rich library support makes it the preferred tool in these areas.

To maximize the efficiency of learning Python in a limited time, you can use Python's datetime, time, and schedule modules. 1. The datetime module is used to record and plan learning time. 2. The time module helps to set study and rest time. 3. The schedule module automatically arranges weekly learning tasks.

Python excels in gaming and GUI development. 1) Game development uses Pygame, providing drawing, audio and other functions, which are suitable for creating 2D games. 2) GUI development can choose Tkinter or PyQt. Tkinter is simple and easy to use, PyQt has rich functions and is suitable for professional development.
