如何划分两个数组并防止零除法

def divide_arrays(array1, array2, threshold):
    # 划分第一个数组
    array1_greater = []
    array1_less_equal = []
    for num in array1:
        if num > threshold:
            array1_greater.append(num)
        else:
            array1_less_equal.append(num)
    
    # 划分第二个数组
    array2_greater = []
    array2_less_equal = []
    for num in array2:
        if num > threshold:
            array2_greater.append(num)
        else:
            array2_less_equal.append(num)
    
    # 处理零除法错误
    if threshold == 0:
        # 可以选择将特定值为零的元素排除在划分之外
        array1_less_equal = [num for num in array1_less_equal if num != 0]
        array2_less_equal = [num for num in array2_less_equal if num != 0]
    
    return array1_greater, array1_less_equal, array2_greater, array2_less_equal

# 示例用法
array1 = [1, 2, 3, 4, 5]
array2 = [6, 7, 8, 9, 10]
threshold = 3

array1_greater, array1_less_equal, array2_greater, array2_less_equal = divide_arrays(array1, array2, threshold)

print("Array 1 Greater:", array1_greater)
print("Array 1 Less or Equal:", array1_less_equal)
print("Array 2 Greater:", array2_greater)
print("Array 2 Less or Equal:", array2_less_equal)
