Easter Eggs in Python’s REPL

Recently, I have ran into a funny thing in Python. Try to import antigravity module inside the REPL:

>>> import antigravity

Obviously, it is not the only funny thing hidden somewhere deep in the Python implementation. I researched the topic and I found more examples of easter eggs :grin:.

The best known is import this easter egg:

>>> 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!

There is also nice example which exploits idea of this:

>>> love = this
>>> this is love
>>> love is True
>>> love is False
>>> love is not True or False
>>> love is not True or False; love is love

Also, Python as a truly enterprise ready language has built-in Hello World functionality:

>>> import __hello__
Hello world...
>>> reload(__hello__)
Hello world...
<module '__hello__' from '<frozen>'>

But the funniest thing is IMHO this:

>>> from __future__ import braces
  File "<stdin>", line 1
SyntaxError: not a chance

This exception message definitely made my day :wink:.

If I omitted something, please post a comment and let me know which I have missed.


  1. xkcd: Python!
  2. Module antigravity
