I had python 2.7.5 installed and i wanted to upgrade to 3.5.
So i went to the website and downloaded the installer.
The installer installed python 3.5 succesully.
In adidtion to that i selected the option to include python to the PATH global variable. I use windows 7.

However, i opened the cmd and typed:

```
python --version

```

I got:

```
Python 2.7.5

```
