Unlike most Unix systems and services, Windows does not include a system supported installation of Python. Instead, Python can be obtained from a number of distributors, including directly from the CPython team. Each Python distribution will have its own benefits and drawbacks, however, consistency with other tools you are using is generally a worthwhile benefit.
