Python RecursionError:使用pandas时，相比之下超过了最大递归深度

我正在处理一些地理数据。我想从我已有的纬度和经度中得到一个点对象。我的代码如下所示：

for i in range(len(map_polygon)):
    x = map_polygon.at[i, 'lon'] 
    y = map_polygon.at[i, 'lat']
    map_polygon.at[i, 'point'] = Point(x, y)

但是，我得到以下错误： RecursionError:比较中超出了最大递归深度

我做错了什么？数据帧的长度只有大约20k行

谢谢大家!

PS我已将整个错误信息附在下面：

添加几何体列时，循环并单独设置每个值通常是个坏主意（速度慢），因此您可能希望这样做：

map_polygon['point'] = [Point(p) for p in zip(df.lon, df.lat)]

---

在OP的示例中，

Point（…）

接受两个参数，这里您将一个参数作为元组。可能应该是

[点（*p）表示zip中的p（df.lon，df.lat）]

或

[点（lon，lat）表示zip中的lon，lat（df.lon，df.lat）]

根据shapely的文档，点采用元组或位置参数：“点构造函数采用位置坐标值或点元组参数。”，传递元组意味着更少的打字伟大的
