雅虎天气API 2019类型错误/属性

Question

想在python3.5.3的Raspberry Pi上运行Yahoo 2019天气API。
通过成功运行Yahoo 2.7.10的示例代码验证了Yahoo访问代码。在

所有示例代码： https://gist.github.com/VerizonMediaOwner/e6be950f74c5a8071329f1d9a50e3158#file-weather_ydn_sample-py

运行2to3转换并收到指示的以下脚本类型错误：

尝试了3.7代码示例并收到AttributeError:

^{pr2}$

请求帮助运行3.5中的一个或另一个。在

Answer 1

决议： 在python3.7的示例代码中，将头import urllib更改为import urllib.request。在这个改变之后，使用Raspberry pipython3.5.3就可以正常工作了。在
