您好我正试图通过使用foor循环索引字典来绘制谷歌地图中的点数,请使用此lat字典:long
latlon = {32.1243973: -101.8856125, 32.666694: -104.233502, 32.222012:
-101.819122, 32.53151: -103.353018, 32.668496: -104.235722, 32.1041336: -101.8818588}
我有这段代码:
if __name__ == "__main__":
map = Map()
for latitude, longitude in latlon.iteritems():
map.add_point(latitude, longitude)
我收到错误 TypeError:add_point()只需要2个参数(给定3个)
我只给出经度和经度为什么它说我给出3个参数?
提前致谢!
编辑:添加类地图:
class Map(object):
def __init__(self):
self._points = []
def add_point(self, coordinates):
self._points.append(coordinates)
def __str__(self):
centerLat = sum(( x[0] for x in self._points )) / len(self._points)
centerLon = sum(( x[1] for x in self._points )) / len(self._points)
markersCode = "\n".join(
[ """new google.maps.Marker({{
position: new google.maps.LatLng({lat}, {lon}),
map: map
}});""".format(lat=x[0], lon=x[1]) for x in self._points
])
return """

答案 0 :(得分:1)
add_point
似乎想要纬度&amp;经度作为单一对象;像这样的东西:
for ll in latlon.iteritems():
map.add_point(ll)
答案 1 :(得分:0)
addPoint()应该将两个坐标作为一个参数。
撰写map.addPoint(p)
的另一种方式是Map.addPoint(map, p)
。从第二个示例中,您可以看到有太多参数导致错误的原因。
您可以像这样调用您的函数,在一个参数中包含纬度和经度:
for i in latlon.iteritems:
map.addPoint(i)
