如何在python中拆分GPS数据？

import re

def split_gps_data(gps_data):
    # 使用逗号分割GPS数据
    data_list = gps_data.split(',')

    # 使用正则表达式提取经纬度信息
    pattern = r'(\d+\.\d+)([NS]),(\d+\.\d+)([EW])'
    match = re.search(pattern, gps_data)
    if match:
        latitude = float(match.group(1))
        longitude = float(match.group(3))
        lat_direction = match.group(2)
        lon_direction = match.group(4)
        return latitude, longitude, lat_direction, lon_direction
    else:
        return None

# 示例用法
gps_data = "39.9087N,116.3975E,100"
result = split_gps_data(gps_data)
if result:
    latitude, longitude, lat_direction, lon_direction = result
    print("纬度：", latitude)
    print("经度：", longitude)
    print("纬度方向：", lat_direction)
    print("经度方向：", lon_direction)
else:
    print("无效的GPS数据")
