为了正确计算地球上各点之间的距离，您需要使用Haversine公式。使用此答案中提供的Python实现，您可以像这样进行编码：
from math import cos, asin, sqrtdef distance(lat1, lon1, lat2, lon2): p = 0.017453292519943295 a = 0.5 - cos((lat2-lat1)*p)/2 + cos(lat1*p)*cos(lat2*p) * (1-cos((lon2-lon1)*p)) / 2 return 12742 * asin(sqrt(a))def closest(data, v): return min(data, key=lambda p: distance(v['lat'],v['lon'],p['lat'],p['lon']))tempDataList = [{'lat': 39.7612992, 'lon': -86.1519681}, {'lat': 39.762241, 'lon': -86.158436 }, {'lat': 39.7622292, 'lon': -86.1578917}]v = {'lat': 39.7622290, 'lon': -86.1519750}print(closest(tempDataList, v))
