如何从csv字符串中获取地图

import csv
from io import StringIO

# 示例CSV字符串
csv_string = "name,latitude,longitude\n"
csv_string += "location1,30.657,104.066\n"
csv_string += "location2,31.231,121.474\n"

# 将CSV字符串转换为列表
csv_list = []
csv_file = StringIO(csv_string)
csv_reader = csv.reader(csv_file)
for row in csv_reader:
    csv_list.append(row)

# 将CSV数据转换为地图信息
map_data = {}
for row in csv_list[1:]:
    location = row[0]
    latitude = float(row[1])
    longitude = float(row[2])
    map_data[location] = {"latitude": latitude, "longitude": longitude}

print(map_data)

{
    'location1': {'latitude': 30.657, 'longitude': 104.066},
    'location2': {'latitude': 31.231, 'longitude': 121.474}
}
