我有一个用户输入的坐标列表，如何计算与所有坐标尽可能接近的点？

import math

def calculate_distance(coord1, coord2):
    # 计算两个坐标之间的欧几里得距离
    x1, y1 = coord1
    x2, y2 = coord2
    distance = math.sqrt((x2 - x1)**2 + (y2 - y1)**2)
    return distance

def find_closest_point(coordinates):
    min_distance = float('inf')
    closest_point = None

    for i in range(len(coordinates)):
        total_distance = 0

        for j in range(len(coordinates)):
            if i != j:
                distance = calculate_distance(coordinates[i], coordinates[j])
                total_distance += distance

        if total_distance < min_distance:
            min_distance = total_distance
            closest_point = coordinates[i]

    return closest_point

# 示例坐标列表
coordinates = [(1, 2), (3, 4), (5, 6), (7, 8)]

closest_point = find_closest_point(coordinates)
print("与所有坐标尽可能接近的点是：", closest_point)
