You want to add water to the fishtank that is as close as possible to the tank temperature. Preferably, slightly warmer rather than cooler. If you can adjust it with the faucets you should. Some people say warm tap water has a slightly different compostion than cold tap water, but its not as important as matching the temp. If you have to use cold water, you need to fill it up really slowly, which kind of defeats the purpose of using the python.
