python - Turn a 1D array into nD array? -


this question has answer here:

i have 784 element 1-dimensional array flattened 28x28 image.

is there nice, snappy, numpy/scipy procedure translating 784 element array 28x28 array?

or have do: 

for in range(0,28):     j in range(0,28):            my_image[i,j] = oned_vector[28*i + j]

reshape() works:

a = np.arange(784) a.reshape(28, 28)
