python - Python中的矩阵转置

Question

我正在尝试为 python 创建一个矩阵转置函数，但我似乎无法使其工作。 说我有

theArray = [['a','b','c'],['d','e','f'],['g','h','i']]

我希望我的功能能够提出

newArray = [['a','d','g'],['b','e','h'],['c', 'f', 'i']]

换句话说，如果我要将这个二维数组打印为列和行，我希望行变成列，列变成行。

到目前为止我做了这个，但它不起作用

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

Answer 1

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')]
