CosmoloPy is a package of cosmology routines for Python, designed for use with NumPy and SciPy. Reionization is a particular focus. See below for a longer list of capabilities.
Functions take cosmological parameters (which can be numpy arrays) as keywords, and ignore any extra keywords. This means you can make a dictionary of all of your cosmological parameters and pass it to any function.
Example
Calculate the comoving distance to redshift 6.
>>> import cosmolopy.distance as cd
>>> cosmo = {'omega_M_0':0.3, 'omega_lambda_0':0.7, 'omega_k_0':0.0, 'h':0.72}
>>> d_co, err = cd.comoving_distance(6., **cosmo)
>>> print "Comoving distance to z=6 is %.1f Mpc" % (d_co)
Comoving distance to z=6 is 8017.8 Mpc
