在python列表中找到点之间最短距离的更干净的方法？

import math

def calculate_distance(point1, point2):
    x1, y1 = point1
    x2, y2 = point2
    distance = math.sqrt((x2 - x1)**2 + (y2 - y1)**2)
    return distance

def find_shortest_distance(points):
    distances = []
    for i in range(len(points)):
        for j in range(i+1, len(points)):
            distance = calculate_distance(points[i], points[j])
            distances.append(distance)
    shortest_distance = min(distances)
    return shortest_distance

# 示例用法
points = [(1, 2), (3, 4), (5, 6), (7, 8)]
shortest_distance = find_shortest_distance(points)
print("最短距离：", shortest_distance)
