我正在制作一张地图，突出显示我所属组织中不同成员类型的国家/地区。我正在与cartopy一起制作这张地图，并以三种不同形状的蓝色突出显示三种类型的成员。 但是，每次我在Python启动器中运行此脚本时，都会不断收到此错误：
`Samuels-MacBook-Pro:IAPS samuelmathiasborer$ python3 map2018.py
Traceback (most recent call last):
File "map2018.py", line 303, in <module>
if country.attributes['adm0_a3'] in NCs:
KeyError: 'adm0_a3'`
我不确定为什么会显示此错误，因为我相信自己使用正确。任何帮助将不胜感激！

答案 0 :(得分：0)
您应尝试使用“ ADM0_A3”而不是“ adm0_a3”。在我看来，他们在今年的某个时候进行了更改。
