...for example:

A = np.random.rand(5,5)

In [366]: A
Out[366]:
array([[ 0.36380049,  0.26440478,  0.8515609 ,  0.07893608,  0.48084575],
       [ 0.71133527,  0.90912083,  0.14812865,  0.23223621,  0.49983985],
       [ 0.51668793,  0.73303799,  0.18620246,  0.52968823,  0.51904697],
       [ 0.3988893 ,  0.60350318,  0.63808109,  0.38470785,  0.48923821],
       [ 0.02427049,  0.80382225,  0.42494655,  0.8986108 ,  0.39879547]])

In [367]: np.nonzero(A==np.min(A))
Out[367]: (array([4]), array([0]))
