Specify Python version #27

Greetings,

I am writing a replication paper on the CodeTransformer for the data mining class at my university.
Unfortunately, I cannot find any specification of the Python version that was used for the experiments.
Inferring from torch==1.4.0 from the requirements.txt file, I figured that Python 3.7 might have been the used version, as this is the most recent Python version supporting torch 1.4.0 (juding by the "Programming languages" section athttps://pypi.org/project/torch/1.4.0/).
I would be very grateful if you specified the used Python version, even though the release of your paper dates a while back.

Thanks and best regards,
Philipp
