python矩阵的转置和逆转实例

# 矩阵的转置
def transpose(list1):
 return [list(row) for row in zip(*list1)]
 
list1 = [[1, 4], [2, 5], [3, 6]]
print(transpose(list1)) # [[1, 2, 3], [4, 5, 6]]

# 矩阵逆转
def invert(list1):
 return [row[::-1] for row in list1]
list1 = [[1, 4], [2, 5], [3, 6]]
print(invert(list1)) # [[4, 1], [5, 2], [6, 3]]
