使用python，我可以并行复制一条x，y，z点的直线，这样x和z保持不变，而y以指定的间距增加吗？

import numpy as np

def copy_line(x, y, z, spacing, num_copies):
    # 计算y的增量
    delta_y = spacing * np.arange(1, num_copies+1)
    
    # 复制x、y、z点的直线
    new_x = np.tile(x, num_copies)
    new_y = np.tile(y, num_copies) + np.repeat(delta_y, len(y))
    new_z = np.tile(z, num_copies)
    
    return new_x, new_y, new_z

# 示例数据
x = [1, 2, 3]
y = [4, 5, 6]
z = [7, 8, 9]
spacing = 2
num_copies = 3

# 复制直线
new_x, new_y, new_z = copy_line(x, y, z, spacing, num_copies)

# 打印结果
print("原始直线：")
print("x:", x)
print("y:", y)
print("z:", z)
print("复制后的直线：")
print("x:", new_x)
print("y:", new_y)
print("z:", new_z)

原始直线：
x: [1, 2, 3]
y: [4, 5, 6]
z: [7, 8, 9]
复制后的直线：
x: [1, 2, 3, 1, 2, 3, 1, 2, 3]
y: [6, 7, 8, 10, 11, 12, 14, 15, 16]
z: [7, 8, 9, 7, 8, 9, 7, 8, 9]
