如何将两个数组组合成一个有内部列表的列表？

def combine_arrays(arr1, arr2):
    result = []
    for item1 in arr1:
        for item2 in arr2:
            combined_list = [item1, item2]
            result.append(combined_list)
    return result

# 示例用法
array1 = [1, 2, 3]
array2 = ['a', 'b', 'c']
combined = combine_arrays(array1, array2)
print(combined)

[[1, 'a'], [1, 'b'], [1, 'c'], [2, 'a'], [2, 'b'], [2, 'c'], [3, 'a'], [3, 'b'], [3, 'c']]
