== What is Python? ==
 Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built in data structures, combined with dynamic typing and dynamic binding, make it very attractive for Rapid Application Development, as well as for use as a scripting or glue language to connect existing components together.

=== Python 2 or 3 ===
Python 3 was incompatible with Python 2.
==== Python2 ====
The last version of Python 2, released in 2010, was Python 2.7. The support for this version ended on January 1, 2020. 
{{{
# HELLO PYTHON
import datetime
import socket

now = datetime.datetime.now()
print 'Hello, world!'
print now.isoformat()
print socket.gethostname()
}}}

==== Python3 ====
Python 3 was not just another version of Python 2 code.  Python 3 came with a new syntax intended to prevent redundant or repetitive code. 
{{{
# HELLO PYTHON
import datetime
import socket

now = datetime.datetime.now()
print('Hello, world!')
print(now.isoformat())
print(socket.gethostname())
}}}
