How to merge multiple MODIS swaths into one plot in python?

I want to mosaic/merge multiple swaths of the MODIS dataset (MOD06_L2) using python. I used the example (http://hdfeos.org/zoo/MORE/LAADS/MOD/MOD04_L2_merge.py) to read multiple files and merge. But I am getting an error while doing so, how to correct this error?

I would like to know is there any better way than this, to merge/mosaic MODIS HDF files into one?
