# Python学习日记：探索编程的奇妙世界
## 2026年1月13日 星期二 多云
今天是学习Python的第11天，我深入研究了循环结构和条件语句的高级应用。通过编写一个学生成绩管理系统，我掌握了for循环和while循环的不同使用场景。在实现成绩统计功能时，遇到了逻辑判断的边界条件问题，通过仔细分析和调试，最终解决了数据处理中的异常情况。
上午重点学习了列表推导式和字典推导式的使用，这让我对Python的简洁性有了更深的认识。下午尝试优化代码结构，将重复的功能封装成函数，提高了代码的可读性和复用性。在调试过程中，我学会了使用print语句和断点调试来定位问题。
通过今天的学习，我深刻体会到编程不仅仅是写代码，更重要的是培养逻辑思维能力。每一个小问题的解决都带来成就感，也让我更加热爱编程这门艺术。明天计划学习文件操作和异常处理，期待掌握更多实用技能。

今天学习了函数定义和模块化编程，这是Python编程的重要概念。我将昨天的学生成绩管理系统重构为模块化结构，把不同功能分别封装到独立的函数中。通过实践，我理解了函数参数传递、返回值和作用域的概念。
在编写过程中，遇到了变量作用域的问题，局部变量与全局变量的混淆导致了逻辑错误。通过查阅资料和调试，我学会了使用global关键字和return语句来正确处理变量作用域。这让我认识到良好的代码结构对项目维护的重要性。
