Author:Francesc Altet
Author:Ivan Vilata i Balaguer

This document details the modifications to PyTables since version 1.2. Its main purpose is help you ensure that your programs will be runnable when you switch from PyTables 1.2 to PyTables 1.3.1.

API additions

  • The Table.Cols accessor has received a new __setitem__() method that allows doing things like:

    table.cols[4] = record table.cols.x[4:1000:2] = array # homogeneous column table.cols.Info[4:1000:2] = recarray # nested column

Backward-incompatible changes

  • None

Deprecated features

  • None

API refinements

  • Table.itersequence has changed the default value for ‘sort’ parameter. It is now False by default, as it is not clear if this actually accelerates the iterator, so it is better to let to the user doing the proper checks (if he is interested at all).

Bug fixes (affecting API)

  • None

Enjoy data!
