python怎么通过调用列表中的多个点的经纬度坐标的元组计算两点间距离，并在输出结果中显示结果显示两点名称,不用geopy库

你好，关于你的问题，你可以使用以下的代码来计算两个坐标点之间的距离：

from math import radians, sin, cos, acos

def distance(lat1, lon1, lat2, lon2):
    """
    Calculate the distance between two points using the haversine formula
    """
    earth_radius = 6371  # in kilometers

    # convert decimal degrees to radians
    lat1, lon1, lat2, lon2 = map(radians, [lat1, lon1, lat2, lon2])

    # haversine formula
    dlat = lat2 - lat1
    dlon = lon2 - lon1
    a = sin(dlat/2)**2 + cos(lat1) * cos(lat2) * sin(dlon/2)**2
    c = 2 * acos(a)

    # calculate the distance
    distance = earth_radius * c
    return distance

# sample data
locations = [
    {'name': 'Location 1', 'coordinates': (39.986749, 116.268007)},
    {'name': 'Location 2', 'coordinates': (39.980114, 116.313288)},
    {'name': 'Location 3', 'coordinates': (39.948938, 116.365868)}
]

# calculate the distances for all pairs of locations
for i in range(len(locations)):
    for j in range(i+1, len(locations)):
        loc1 = locations[i]
        loc2 = locations[j]
        dist = distance(loc1['coordinates'][0], loc1['coordinates'][1],
                             loc2['coordinates'][0], loc2['coordinates'][1])
        print(f"{loc1['name']} and {loc2['name']} are {dist:.2f} kilometers apart.")

在上面的示例代码中，我们使用了海卫氏公式来计算地球上两个坐标点之间的距离。示例数据包含三个位置和它们的坐标点。我们使用嵌套循环来计算每对位置之间的距离，并将结果显示在屏幕上。

希望这可以帮助您解决问题。如果您有其他问题，请随时问我。
