如何使用 python 修复 Geocoder 中的关键错误 0

Question

我正在尝试从数据框中的一列地址映射出纬度和经度。但它一直给我关键错误 0.

for i in range(len(df['addresses'])):
    g = geocoder.arcgis(df['addresses'][i])
    coordinates.append(tuple(g.latlng))

这是错误信息

在从 OP 获得更多信息后编辑了此答案。

我假设 df 是一个 Pandas 数据框。

这里的问题是 for i in range(len(df['addresses'])): 在每个循环中给你一个整数。然后，您尝试从 Pandas 数据框中获取包含该整数的列表，这会导致 KeyError.

从for循环中取出range和len，你将从addresses列中得到一个地址。然后将该地址传递给 geocoder.

所以，如下：

for address in df['addresses']:
    g = geocoder.arcgis(address)
