I'm trying to use python in powershell

I'm trying to follow Zed Shaw's guide for Learning Python the Hard Way. I need to use python in Powershell. I have Python 2.7.3 installed in C:Python27. Whenever I type python into Powershell, I get an error that says the term 'python' is not recognized as the name of a cmdlet, function, script file, or operable program. I also typed in this: [Environment]::SetEnvironmentVariable("Path", "$env:Path;C:Python27", "User") That was a suggested solution provided, but typing python into Powershell still does nothing. I can type in "start python" and it opens up a window with python but I need it in Powershell. Thanks.

Try setting the path this way:

 $env:path="$env:Path;C:Python27"
