In previous article :  [Tutorial] Install Python in Windows explained you how to do it in Windows. For Python is a Linux Programming friend, its recommended that you develop or learn Python under Linux OS ( Ubuntu etc).

Python is divided into 2 version of development ( version 2 and 3). both have some different syntax . 

So will find that people install on of them ( version 2 or 3). you better avoid installing them in one OS for its documented to have some problems. You need to specify some commands to make them work together (CMIIW). 

Install Python  

Type this in your terminal line by line :
sudo apt-get install build-essential
sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev
The above command will install python dependency libraries for you.

I'd recommend that you install version 2. 

After install dependencies completed, run this in your terminal : 

Extract and go to the dirctory:

tar -xvf Python-2.7.6.tgz
cd Python-2.7.6

now run this to install it
sudo make install

Your Python should be installed.
