Hello all,
In this gist you may find resources in Russian/English which could be useful for writing Python script for test automation tasks.
While Python 3.x (>=3.3) is reccomended for new project development it much better and easier to go with a bit older but rock-solid Python 2.x (>=2.7) for test automation.
Some Python packages comes with binary modules and it much easier to use 32-bit Python under Windows due to this reason.
