在第3章，你将学习如何在被称为列表的变量中存储信息集，以及如何通过遍历列表来操作
其中的信息
写注释 # 代码越长 标识好代码的重要性 越来越重要
要求习惯：在代码中编写清晰，简洁的注释
开始研究更复杂的主题时，尽量将代码写的简洁清晰

bicycle = ['yaojianyun','laojiang','mahongguo',' ouyang']
print("puke is who great? " + bicycle[0].title())
print("majiang is who great? " + bicycle[1].title())
print("putong laoqian is who? " + bicycle[2].title() + bicycle[3].title())

修改列表元素练习 其实和shell数组一个原理 普通人难的是事，是行动，程序员 是用代码和别人说话 ，走路，交谈
