[Numpy-discussion] behaviour of np.loadtxt

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
