Better to ask this at help or tutor @ Python.org. I am sending this to 
help, with a new subject,. Please reply to that address with that subject

Please make the subject meaningful. "Hello" is not.

Please state questions clearly, so we don't have to guess. For now I'll 
guess.

You have opened a "command prompt" and typed "python". You got 'python'' 
is not recognized as an internal or external command, operable program 
or batch file.

If that is true, continue. Otherwise tell us what you did and what you got.

What led you to expect something different? What did you expect?

When I do the above I get

Python 3.3.3 (v3.3.3:c3896275c0f6, Nov 18 2013, 21:19:30) [MSC v.1600 64 
bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
 >>>

Please reply to above questions. The more you tell us the easier it is 
to help.

How did you install python? What version?
