Question

我是编程Python的新手，并且已经做了一些使用下面代码的教程。当我尝试为googlemaps模块定义变量时，我的代码在第二行偶然发现。我从在线教程获得的源代码是从谷歌地图服务器获取路线：https://www.youtube.com/watch?v=PzkHU5GM8_E&list=PLHPcpp4e3JVqYgQFM9NPo_ksEqa_bRH79&t=74

from googlemaps import googlemaps

MS = googlemaps() <-- 'module' object is not callable

我查看了Python 3.4文档区域和模块区域。我曾尝试通过PIP再次下载模块，但无济于事，谷歌也没有提出任何建议。

我确实注意到其他代码有GoogleMaps（有大写字母）我试图调用但是它不存在。我没有尝试过任何其他版本的Python中的代码，但这似乎是一个非常基本的错误。

任何人都能解释一下吗？

Answer 1

该视频适用于以前版本的googlemaps库。在最新版本中，API已更改。如果要安装该（较旧）版本：

pip install googlemaps==1.0.2

然后，您应该将您的导入声明完全写入视频（GoogleMaps）。

Answer 2

要获取最新版本中的路线，您需要使用Client和direction：

from googlemaps import Client

c = Client(key="api_key")

d = c.directions("texarkana","atlanta")

要获得视频中的步骤：

steps = c.directions("texarkana","atlanta")[0]["legs"][0]["steps"]

for d in steps:
    print(d['html_instructions'])
