[Pytables-users] removing rows in a loop

[Kevin C. <kch...@ya...>]

I am having problems removing rows.  Since removeRows() doesn't accept a list of indices to be removed (it only accepts a single value or a range), I tried to remove the rows one by one, where DryExp is my table:

listofBadNums = ['NJ451','AJ322','B321']    #actually this is just a short test list
for row in DryExp:    
    if row['CatalogNum'] in listofBadNums:
        DryExp.removeRows(row.nrow)        
DryExp.flush()

I also tried moving DryExp.flush() inside the loop, but in either case I got the following error message:

Traceback (most recent call last):
  File "D:\tablem.py", line 46, in <module>
    for row in DryExp:
  File "tableExtension.pyx", line 801, in tableExtension.Row.__next__
  File "tableExtension.pyx", line 951, in tableExtension.Row.__next__general
  File "tableExtension.pyx", line 548, in tableExtension.Table._read_records
HDF5ExtError: Problems reading records.

So I suspect the problem is that DryExp is changing every time.

Thanks for any help,

Kevin
