 +Users of curly bracket programming languages, such as C or Java, sometimes expect or wish Python to follow a block-delimiter convention. Brace-delimited block syntax has been repeatedly requested, and consistently rejected by core developers. The Python interpreter contains an easter egg that summarizes its developers'​ feelings on this issue. The code from __future__ import braces raises the exception SyntaxError:​ not a chance.
 +
 +Another hidden message, The Zen of Python (a summary of Python philosophy),​ is displayed when trying to import this.
 +
 +The message Hello world... is printed when the import statement import __hello__ is used.
 +
 +An antigravity module was added to Python 3.0. Importing it opens a web browser to an xkcd comic that portrays a humorous fictional use for such a module, intended to demonstrate the ease with which Python modules enable additional functionality.[10]

 +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!
