[Pytables-users] Table.row.append() strange values

[Stefan K. <pon...@ya...>]

Hi,

If I run this simple loop, I get the output I expect..

table = fp.root.table_0
for row in table:
    print row

but when I call row.append(), the output changes and looks corrupted..

table = fp.root.table_0
for row in table:
    print row
    row.append()

Perhaps I am misunderstanding how row.append works.  I want to iterate
over the data a row at a time, set some values in row and have those
values written back.  

Here is the output when it's ok ( not calling append ) and then when I
do..
