I think that the essence of this question is how to install Python and be able to use it from the command line. The steps below show how to get all that working. Check that you didn't miss anything:

<ol>
<li>From <a href="https://www.python.org/download/releases/2.7.6">https://www.python.org/download/releases/2.7.6</a> download appropriate Python 2.7.6 Windows Installer. (If that link doesn't work, check <a href="https://www.python.org/downloads/">https://www.python.org/downloads/</a>)</li>
<li>Run the file</li>
<li>Select install for all users or install just for me, click Next</li>
<li>You'll see it installs under the C:\Python27 folder, click Next</li>
<li>Click Next again for the 'Customize Python' step</li>
<li>Click Finish</li>
<li>Open Control Panel, then System</li>
<li>Click 'Advanced system settings' on the left</li>
<li>Click the 'Environment Variables' button</li>
<li>Under 'System variables' click the variable called 'Path' then the 'Edit...' button. (This will set it for all users, you could instead choose to edit the User variables to just set python as a command prompt command for the current user)</li>
<li>Without deleting any other text, add <code>C:\Python27;</code> (include the semi-colon) to the beginning of the 'Variable value' and click OK.</li>
<li>Click OK on the 'Environment Variables' window.</li>
</ol>

Open a new command prompt window type <code>python</code>, you will have python running in the command prompt. Note: command prompt windows open prior to setting the Environment Variable will not have the python command available.

Make sure you don't put a space between the semi-colon and the new folder location that you are adding to the path.

For example it should look like...

{last path entry};C:\Python27;C:\Python27\Scripts;

...not...

{last path entry}; C:\Python27; C:\Python27\Scripts;

How to install Python / Pip on Windows Steps

<ol>
<li>Visit the official Python download page and grab the Windows installer for the latest version of Python 3.
python.org/downloads/</li>
<li>Run the installer. Be sure to check the option to add Python to your PATH while installing.</li>
<li>Open PowerShell as admin by right clicking on the PowerShell icon and selecting ‘Run as Admin’</li>
<li>To solve permission issues, run the following command:</li>
</ol>

Set-ExecutionPolicy Unrestricted

<ol start="5">
<li>Next, set the system’s PATH variable to include directories that include Python components and packages we’ll add later. To do this:
C:\Python35-32;C:\Python35-32\Lib\site-packages\;C:\Python35-32\Scripts\</li>
<li>download the bootstrap scripts for easy_install and pip from <a href="https://bootstrap.pypa.io/" rel="nofollow">https://bootstrap.pypa.io/</a>
ez_setup.py
get-pip.py</li>
<li>Save both the files in Python Installed folder
Go to Python folder and run following:
Python ez_setup.py
Python get-pip.py</li>
<li>To create a Virtual Environment, use the following commands:</li>
</ol>

cd c:\python
pip install virtualenv
virtualenv test
.\test\Scripts\activate.ps1
pip install IPython
ipython3
Now You can install any Python package with pip

That’s it !!
happy coding

i'm using python 2.7 in win 8 too but no problem with that. maybe you need to reastart your computer like wclear said, or you can run python command line program that included in python installation folder, i think below IDLE program. hope it help.

So I'm trying python 2.7 on my Windows. It is running Windows 8. I cannot add it to my path. I've done the usual: using the advanced system settings, environment variables, adding <code>C:\Python27</code> in system variables.

However, when I type Python in command prompt it says 'python is not recognized ..'

所以我在Windows上尝试python2.7。它正在运行Windows 8，我不能将它添加到我的路径中。我已经做了通常的工作:使用高级的系统设置、环境变量，在系统变量中添加C:\Python27。但是，当我在命令提示符中输入Python时，它会说'python不被识别.‘
