Bug in Python 3.5.1

[nisthesecond]

    Dear Sir,
   I downloaded and installed Python 3.5.1 in Windows 10.
   The pip command was not part of it.
   In the future, can you kindly include numpy, scipy, and pygame as part of
   the Python release?
   I am a teacher trying to teach Python to my students.
   To get a working version of Python going is extremely tedious.
   Kind Regards,
   Nick Srinivasan
