TypeError: cannot concatenate 'str' and 'float' objects

关于如何解决此错误的任何建议？

Any advice on how I can fix this error?

推荐答案

最简单的解决方案如下所示：

The simplest solution would look like this:

wkt = "POINT("+ str(geoPoint["lat"]) +" " + str(geoPoint["lon"]) + ")"

以下内容将更符合公认的Python风格标准：

The following would be more in line with accepted Python stylistic standards:

wkt = "POINT(%f %f)" % (geoPoint["lat"], geoPoint["lon"])

这使用字符串格式

您还可以做一些更好的事情：

You could do something nicer still:

wkt = "POINT({lat} {lon}".format(**geoPoint)
