[Numpy-discussion] Norm of array of vectors

Sorry if that's a noob question, but anyway. I have several thousands of
vectors stacked in 2d array. I'd like to get new array containing
Euclidean norms of these vectors and get the vector with minimal norm.
Is there more efficient way to do this than
argmin(array([sqrt(dot(x,x)) for x in vec_array]))?
Thanks in advance.
