跟我抓的是一个地方的，偶是把城市和对应ID存到数据库表里去了，哈哈。

我复制粘贴后，执行出来的中文显示是乱码，文件已是UTF8格式了。

你的系统是Linux?

把这一句后面的解码去掉就行了。
result=response.read().decode('utf-8').encode("gbk")

改成：
result=response.read()

我的系统是 Windows XP的
你说的这个方法我试了，我试了后，发现显示 全部都是乱码了

原先的只是部分乱码，见附图！


LZ能分享一下你的源文件吧，不知道是不是文件格式的问题。

windows系统啊，那就不要改代码了，
把源文件的编码从utf-8换成gbk就可以了。

问题解决了，还是文件格式的问题，不应该存成utf-8格式的。
