It runs on 64 bits OS, for once, which generally means the python
process can address more than the few Gb possible under a 32 bits
platform. If you need to deal with big data, this is useful (for
example, with 64 bits python, you can use numpy arrays which take more
4 Gb of memory - it depends on the exact configuration, but most 32
bits OS cannot give more than 2 or 3 Gb to one process).
