 Dear all,

 Just a small question, how can I output different columns of ndarray in
 different formats,
 the manual says, A single format (%10.5f), a sequence of formats, or a
 multi-format string
 but I use

 np.savetxt('new.csv',data,fmt=['%i4','%f6.3'])

 or

 np.savetxt('new.csv',data,fmt=('%i4','%f6.3'))

 give strange results.



I think you've flipped the format codes; try:

fmt = ('%4i', '%6.3f')
