背景意义介绍：
随着社会对高学历人才的需求不断增加，考研成为越来越多大学生的选择。然而，传统的考研学习方式存在信息不集中、资源分散等问题。基于Python的考研学习系统旨在解决这些问题，提供一个集中、便捷的学习平台，整合各类考研资源，提高学习效率。该系统的理论意义在于探索Python技术在教育领域的应用，丰富相关理论体系；实际意义在于帮助考生提高学习效率，减轻学习负担，为我国高等教育事业贡献力量。
该系统通过提供课程信息、考研资料、学习论坛、试题测试和考研资讯等功能，为考研学生创造了一个全面的学习环境。学生可以根据自己的需求浏览和下载课程资源，参与论坛讨论，进行模拟测试，以及获取最新的考研资讯。此外，系统还为教师提供了管理课程资源和发布成绩的功能，有助于教师更好地跟踪学生的学习进度和调整教学策略。
1.技术选型
