如何获取嵌套列表python中每一列的最大值？

def get_column_max_values(nested_list):
    max_values = []
    transposed_list = list(zip(*nested_list))
    for column in transposed_list:
        max_value = max(column)
        max_values.append(max_value)
    return max_values

nested_list = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
column_max_values = get_column_max_values(nested_list)
print(column_max_values)
