python 实现矩阵上下/左右翻转,转置的示例

for i in range(row // 2):  matrix[i], matrix[row-1-i] = matrix[row-1-i], matrix[i]

for m in matrix:  for j in range(col // 2):    m[j], m[col-1-j] = m[col-1-j], m[j]

matrix_T=list(map(list,zip(*matrix)))

matrix=numpy.array(matrix,dtype=int)matrix_T=numpy.transpose(matrix)
