本课程名称为《从零开始学习Python、MySQL与OpenCV，开发加密货币提醒》。课程内容涵盖了Python语言的基础知识以及一系列实用的编程技能，帮助学员掌握Python的基本特性、数据库交互和图像处理。 课程首先介绍Python的安装，包括Visual Studio Code编辑器和相关包的安装。学员将学习基本的Python数据类型，如列表、字典、元组和集合，以及条件语句、循环、函数、lambda函数等基础语法。OOP概念也被引入，解释类和对象的定义以及实例化，同时讲解类的继承以加强对面向对象编程的理解。 接下来，课程深入探讨Selenium WebDriver框架，教授如何进行网页元素检测并实施网页抓取策略，特别是使用显式等待策略来提升性能。学员还将学习MySQL与Postgres数据库的交互，掌握项目所需的数据库查询以及如何处理数据库中数据的存储与删除。 OpenCV2部分将着重于图像像素分析，教导学员如何过滤图像中的相关像素，检测边缘及其坐标，以及计算边缘之间的距离，以便进行效果控制。此外，课程还将介绍如何在Heroku远程主机上部署Python应用，包括相应软件包的安装和从GitHub环境直接部署应用。 课程的一个亮点是构建一个实际的加密货币提醒Python应用，学员将实时获取所有加密货币的价值对，将这些数值存储在数据库中，并根据自定义策略判断是否投资。还将学习如何在Telegram上发送加密货币提醒通知，以及实现自动交易的功能，通过突破安全验证，从而实现无需人工干预的交易。 最后，课程提供了典型的招聘面试问题，帮助学员准备进入Python和网络测试职位的申请，并设置了一个最终开发挑战，确保每位学员都能在实际开发中获得实践经验，课程的完整源代码也随之提供。
