Hi pytablers,
Before I am going to embark on using pytables2, I would like to know how
free I am in choosing the dtype of a column.
I would like to store a momentum in my table.
Currently in pytables1 I am using something like
momentum = Float32Col(shape=3)
But now that I know more about numpy, I am wondering if there is a way to
specify the dtype of momentum, like so
momentum = Float32Col(dtype={'names': ('x','y', 'z'), 'formats': (
N.float32, N.float32, N.float32)})
or something like that.
The other way would be to have momentum a class with three components x, y,
z.
That would be OK, too, but then will I be able to assign the values to the
row all at once?
Something like
row = table.row
row['momentum'] = (1, 2, 3)
Right now I am assigning a new dtype after reading the column, but if feels
like a hack and I would like to be able to read the right dtype from disk.
Thanks a lot,
Jan
