The pwtools package, written by Steve Schmerler, is a Python package for pre- and postprocessing of atomic calculations, mostly targeted to Quantum Espresso, CPMD, CP2K and LAMMPS. It is almost, but not quite, entirely unlike ASE, with some tools extending numpy/scipy. It has a set of powerful parsers and data types for storing calculation data.

The project is hosted at: https://bitbucket.org/elcorto/pwtools

    $ python
    >>> from pwtools import dcd
    >>> cc,co = dcd.read_dcd_data_py('cp2k.dcd')

Afterwards cc will conatain the unit cell parameters and for each step (a,b,c,alpha,beta,gamma), and co will contain the Cartesian coordinates in Angstrom.
