给定以下数组，如何将其打印到多行

def print_multi_lines(array, num_per_line):
    for i in range(0, len(array), num_per_line):
        print(array[i:i+num_per_line])

# 示例数组
array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]
# 每行打印4个元素
num_per_line = 4

print_multi_lines(array, num_per_line)

[1, 2, 3, 4]
[5, 6, 7, 8]
[9, 10, 11, 12]
[13, 14, 15]
