People may know or not know about this fact, based on their knowledge or experience. Will the new installation overwrite that folder, etc. Python has Lib/site-packages folder with my packages inside. It's a simple and direct question, let me make it clearer: e.g. Thanks for the comments, but as my understanding, this site is about Q&A: got question & get answered. (If there will be a lot of hassles, then perhaps I'll follow the mantra: "if it is not broken, don't fix it".) Do I need to re-install/reconfigure the packages again? As the logic, Python 2.7.9 will also be in the same folder Python27 (as 2.7.6). (2) will it break/overwrite the current setup of my 2.7.6 environment? I notice there are 2 folders on my C:\, which are Python27 and Python33. (1) is it worth upgrading from 2.7.6 to 2.7.9, any benefit in performance, security, stability.? I see that Python released the newer version: 2.7.9.

I didn't follow the "easy" way of installing all-in-one Anaconda or Enthought Canopy software, instead I installed packages one by one (using pip.), some packages,(scipy, sympy, pandas, lxml) could not be installed by pip and I had to installed using a MSI file. It took me quite a lot of effort at the beginning to set up the environment ready for my works. However due to the compatibility with the required packages (openCV, Numpy, Scipy, etc.) and the legacy code, I work most of the time with Python 2.7.6. I have both version of Python on my system: 3.3.2 and 2.7.6.
