[Pytables-users] Modifying existing rows in a table?

[Norbert N. <Nor...@gm...>]

Hi there,

i would have assumed that the following works:
-------------------------
#!/usr/bin/env python

from tables import *

file = openFile('tryout.h5','w')

desc = {}
desc['x'] = FloatCol()

file.root.mytable = Table(desc)
mytable = file.root.mytable

row = mytable.row
for i in range(3):
    row['x'] = i
    row.append()
mytable.flush()

for row in mytable.iterrows():
    row['x'] = row['x'] + 0.5
mytable.flush()

for row in mytable.iterrows():
    print row['x']

file.close()
-------------------------

but obviously, the writing is completely ignored. Is this intuitive approach 
wrong? Is it just not implemented yet? Is there some other way the same thing 
could be done?

Ciao,
Norbert
