[See bottom notes about why **Python 2**, not 3]. 2. Open PowerShell and type _python_ 3. If you get an error define the environment variable to know about python <pre class="lang:ps decode:true ">[ENVIRONMENT]::SETENVIRONMENTVARIABLE("PATH", "$ENV:PATH;C:\PYTHON27", "USER")</pre>
Close PowerShell and open it again and try _python_ again.
If done right, you should see something like this:

To exit Python you can type _exit()_</li> </ol>
Note: Why Python 2 vs Python 3 to get started:
> A programmer may try to get you to install Python 3 and learn that. Say, “When all of the Python code on your computer is Python 3, then I’ll try to learn it.” That should keep them busy for about 10 years. I repeat, _do not use Python 3_. Python 3 is not used very much, and if you learn Python 2 you can easily learn Python 3 when you need it. If you learn Python 3 then you’ll still have to learn Python 2 to get anything done. Just learn Python 2 and ignore people saying Python 3 is the future.
