Examples

>>>importnumpyasnp>>>x=np.arange(1,7).reshape(2,3)>>>xarray([[1, 2, 3],       [4, 5, 6]])>>>x.flat[3]4>>>x.Tarray([[1, 4],       [2, 5],       [3, 6]])>>>x.T.flat[3]5>>>type(x.flat)<class 'numpy.flatiter'>

An assignment example:

>>>x.flat=3;xarray([[3, 3, 3],       [3, 3, 3]])>>>x.flat[[1,4]]=1;xarray([[3, 1, 3],       [3, 1, 3]])
