Need help for beginning coding

Python is already installed in Ubuntu 16.04. Open a terminal and type python. You should see something like this:

Output:
victor@jerry:~$ python
Python 2.7.12 (default, Nov 19 2016, 06:48:10) 
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> 

This is the Python interpreter and you can see the Python's version. It can be 3.5.2 if it's configured as the default. You can run 2.7.12 with python2 command if that is the case.
