我正在尝试为python创建矩阵转置函数,但似乎无法使其工作。说我有
theArray = [['a','b','c'],['d','e','f'],['g','h','i']]
我想提出我的职能
newArray = [['a','d','g'],['b','e','h'],['c', 'f', 'i']]
因此,换句话说,如果我要将此2D数组打印为列和行,我希望将行变成列,将列变成行。
我到目前为止已经做到了,但是没有用
def matrixTranspose(anArray): transposed = [None]*len(anArray[0]) for t in range(len(anArray)): for tt in range(len(anArray[t])): transposed[t] = [None]*len(anArray) transposed[t][tt] = anArray[tt][t] print transposed
Python 2:
>>> theArray = [['a','b','c'],['d','e','f'],['g','h','i']] >>> zip(*theArray) [('a', 'd', 'g'), ('b', 'e', 'h'), ('c', 'f', 'i')]
Python 3:
>>> [*zip(*theArray)] [('a', 'd', 'g'), ('b', 'e', 'h'), ('c', 'f', 'i')]
