你可以这样使用列表解析：

point_list = [(54,8),(55,9),(56,10),(57,11)]

split_points = [[point_list[i], point_list[(i+1) % len(point_list)]] for i in range(len(point_list))]

print(split_points)

输出：

[[(54, 8), (55, 9)], [(55, 9), (56, 10)], [(56, 10), (57, 11)], [(57, 11), (54, 8)]]

正如@JonSG所建议的，前面的拼接方法需要一个额外的append：

point_list = [(54,8),(55,9),(56,10),(57,11)]

split_points = [point_list[i:i+2] for i in range(len(point_list)-1)]
split_points.append([point_list[-1], point_list[0]])

print(split_points)

要使用点对，您可以执行以下操作：

def print_coordinates(x1, y1, x2, y2):
    print(x1, x2, y1, y2)

for point1, point2 in split_points:
    print_coordinates(*point1, *point2)
