Python 2.7 not working in Windows Console

I recen开发者_运维技巧tly upgraded from python 2.6 to python 2.7 and everytime I try todo python setup.py install I get.

'python' is not recognized as an internal or external command,
operable program or batch file.

It worked fine with 2.6.

That error sounds like the python (or python.exe in case you are on windows ) binary is not in your PATH.
