将Lat / Long传递给geolocator

Question

python的新手，我有一个带lat / long的cvs文件，我正在尝试检索地址，如何将我的lat / long字符串传递给geolocator

with open('try.csv', 'rb') as f:
   reader = csv.DictReader(f)
   for row in reader:
    geolat = row['pickup_latitude']
    geolong = row['pickup_longitude']
    # point = Point(float(row['pickup_latitude']),     float(row['pickup_longitude']))

    val1 = ("\""+geolat+", ")
    val2 = (geolong+"\"")
    val = val1 + val2
    print val
# var returns "40.750912, -73.99102"
location = geolocator.reverse(val)

Answer 1

geolocator.reverse接受一个以逗号分隔的字符串作为其参数。

with open('try.csv', 'rb') as f:
    reader = csv.DictReader(f)
    for row in reader:
        geolat = row['pickup_latitude']     # geolat is a string
        geolong = row['pickup_longitude']   # geolong is a string
        latlong = [geolat, geolong]         # latlong is a list of two strings
        val = ", ".join(latlong)            # val is one comma-separated string

        location = geolocator.reverse(val)
        print(location)

当然，您可以牺牲可读性来削减所有中间步骤。

with open('try.csv', 'rb') as f:
    reader = csv.DictReader(f)
    for row in reader:
        location = geolocator.reverse(", ".join([row['pickup_latitude'], row['pickup_longitude']]))
        print(location)

Rembember，Python中的行缩进约定是4个空格。
