10 Easter Eggs in Python

Have you heard about Python Easter eggs? In this article, we will discuss the 10 best Easter eggs in Python.

1.Simple Hello World

This Easter egg will print a hello world message. Open the python terminal and try this code.

>>> import __hello__
Hello world!

Hello world can be printed using importing __phello__.

>>> import __phello__
Hello world!

2. The Zen of Python

As per the PEP20 , “The zen of Python” is written by Tim Peters it has 20 lines describing the guiding principles of Python’s design.

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!

3. The comics, Antigravity!

Experience the antigravity using single line of code!

import antigravity

Try it out, it will open xkcd web comic page.

4. The braces.

Official python does not support curly braces but it might change in the future. Let’s try to import braces from __future__ .

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

5. Hash of Infinity and NaN

Python provides a hash function. The hash of infinity and NaN(Not a Number) :

>>> hash(float('inf'))
>>> hash(float('nan'))

The original reference of this Easter egg from Reddit.

6. Uncle Barry

A well-known Python developer Barry Warsaw (aka Uncle Barry) was ‘chosen’ to become the Friendly Language Uncle For Life (FLUFL).

He introduced some modifications PEP 401, replacement of inequality operator (!=) by diamond operator(<>). If you want to use this feature or Uncle Barry’s vision just import it from __future__.

from __future__ import barry_as_FLUFL

>>> 10 != 50
  File "<stdin>", line 1
    10 != 50
SyntaxError: with Barry as BDFL, use '<>' instead of '!='

But if we use diamond operator it will not show error.

>>> from __future__ import barry_as_FLUFL
>>> 10 <> 50

 7.Python 3.9 PEG parser

The __peg_parser__ is a keyword introduced in Python 3.9 . It will throw error if we use it.

>>> __peg_parser__
  File "<stdin>", line 1
SyntaxError: You found it!

8. Warning – Not for the faint of heart !

If we check the help for types.CodeType then it will show text “Not for the faint of heart”.

>>> import types
>>> help(types.CodeType)
Help on class code in module builtins:                                                    
class code(object)                                                                        
 |  code(argcount, kwonlyargcount, nlocals, stacksize, flags, codestring,                 
 |        constants, names, varnames, filename, name, firstlineno,                        
 |        lnotab[, freevars[, cellvars]])                                                 
 |  Create a code object.  Not for the faint of heart.                                    
 |  Methods defined here:                                   

9. Picking a place for meetup?

This is based on Geohashing , geohash function will compute a destination coordinates. For calculating meeting location, we have to give location coordinates and date.

>>> from antigravity import geohash
>>> # Your location, a date and that date's (or most recent) DJIA opening.
>>> geohash(37.421542, -122.085589, b'2005-05-26-10458.68')
37.857713 -122.544543

Help for geohash function

>>> help(geohash)
Help on function geohash in module antigravity:

geohash(latitude, longitude, datedow)
    Compute geohash() using the Munroe algorithm.

10. The this.py

Let ‘s explore the source of The Zen of Python , this.py.

d = {}
for c in (65, 97):
    for i in range(26):
        d[chr(i+c)] = chr((i+13) % 26 + c)

print("".join([d.get(c, c) for c in s]))

Yes, the string “s” is encrypted, it is ROT13 “rotate by 13 places” encrypted. It is special case of Caesar cipher.
