Dear list,

I'm encountering a problem with np.loadtxt.

Suppose i have a file containing three columns of data (and 10 rows), like:

0.001 0.003 0.005 0.001 0.003 0.006 0.002 0.004 0.002 0.004 0.002 0.007 0.001 0.003 0.006 0.002 0.004 0.002 0.004 0.002 0.007 0.001 0.003 0.006 0.002 0.004 0.002 0.004 0.002 0.007

If i give:

len ( np.loadtxt( filename, unpack=True ) )

i get 3, since i have a three rows array. That's fine.

If instead the file has a single column, i.e.,

0.004 0.002 0.007 0.004 0.002 0.007 0.004 0.002 0.007 0.004

the command

len ( np.loadtxt( filename, unpack=True ) )

returns 10, where i would expect it to return 1, to be consistent with the behaviour when there are multiple columns.

Is there a reason for why it is not like that?

Cheers
