我已经开始学习python编程了,我正在做一个交给我的项目。当我输入的时候,它说的是无效选项。我不能解决这个问题。我不知道我做错了什么。我知道的每件事都试过了。请帮帮我! 我的输出 python自行车用品.py你知道吗
你好!让我们来探索一些美国自行车共享数据! 请输入您想探索的城市编号: 芝加哥1号,纽约2号,华盛顿3号
1 Invalid choice... Please enter the number of which city you would like to explore: 1 Chicago, 2 New York City, 3 Washington
谢谢你的帮助

代码和我一起工作。。。你怎么办?你知道吗
您的比较是以字符串形式查找数字。如果您使用标准输入(例如,在终端中运行),那么它将以字符串的形式读入。但是,如果您以某种方式传入一个整数,那么它将不匹配。你知道吗
