Powershell does not recognize Python

I have installed Python 2.7.10 but Powershell does not recognize it. I have tried the following:

  1. Entering [Environment]::SetEnvironmentVariable(“Path”, “$env:Path;c:\Python27”, “User”)
  2. Closing and re-opening Powershell
  3. Restarting Windows
  4. Uninstalling and re-installing Python 2.7.1 (Could not find the “install Python in path” option in the installer window even in Advanced settings)
    Please help.
    Windows version: Windows 10 Enterprise | 64-bit OS

Make sure you check the check box that says to add Python to the PATH when you did the install, then restart your computer.
