Did you know that if you type import this at a modern Python interpreter, you get the Zen of Python?

So open a Python interpreter and type: import this

>>> import this
The Zen of Python, by Tim Peters

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.
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!

So when you type import this on the python ide you get the Zen Of Python as an output.It is a collection of 20 software principles that influences the design of Programming Language.
It was included as an easter egg in python interpreter and is also an informational entry number 20 in Python Enhancement Proposal(PEP)

The this module was introduced from pyhton 2.2 and it is nothing but the humour of CPython core developer Tim Peters.I mean just look at the odds there is "this.py" module in python interpreter which does nothing but prints the zen of python.
This was all back in the day when Python community had a sense of humour.
