嵌套的列表推导式（可以转置行列）学习

代码练习

list1=[
    [1,2,3,4,5],
    [6,7,8,9,10],
    [11,12,13,14,15]
]
print(list1)
result1=[[list2[i] for list2 in list1] for i in range(len(list1[0]))]
print(result1)
result2=[[list3[i] for list3 in result1] for i in range(len(result1[0]))]
print(result2)
'''zip-test'''
print(list(zip(*result2)))
# print(list(zip(result2)))
