3. About Python
From the official website:
Python is a remarkably powerful dynamic programming
language that is used in a wide variety of application domains.
Python is often compared to Tcl, Perl, Ruby, Scheme or Java.

4. Features
clear syntax
introspection
multiparadigm (OO, procedural, functional, ...)
very high level dynamic data types (lists, sets, maps, ...)
“batteries included” + 3rd party modules for virtually every task
extensions and modules in C, C++ (or Java for Jython, or .NET
languages for IronPython)
embeddable within applications as a scripting interface (e.g.: games)
extensive unittest support
docstrings

5. >‌>‌> import this (The Zen of Python)
Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren’t special enough to break the rules.
Although practicality beats purity.

6. >‌>‌> import this (The Zen of Python)
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.
There should be one – and preferably only one – obvious way to do it.
Although that way may not be obvious at first unless you’re Dutch.
Now is better than never.
Although never is often better than *right* now.
If the implementation is hard to explain, it’s a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea – let’s do more of those!
