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

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

[Numpy-discussion] output different columns of ndarray in different formats

2011-12-22 Thread Chao YUE 
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.

In [33]: data.shape
Out[33]: (6506, 2)

I want the first column integer and second column float.

cheers,

Chao
