-## Notes
-1. Easiest hello world program in a language without calling any function
-2. Each and every line is the philosophy of Python's design and is a supreme holy guide
-3. Maybe just to show that there always should be a new line at the end of a file!
-4. Not an easter egg, a joke in the interpreter
-5. It opens this [xkcd comic](https://xkcd.com/353) which demonstrates how easy it is to do stuff with modules
-6. This is to instantly close down any conversation about introducing curly braces to Python
-7. Guido van Rossum is a big fan of [Monty Python's Flying Circus](https://en.wikipedia.org/wiki/Monty_Python%27s_Flying_Circus)
-8. It's a substitution cipher called [ROT13](https://en.wikipedia.org/wiki/ROT13)
-9. In many languages there are two ways to do the same thing `--no` and `no--`. The message has a hidden example in itself
-10. Support for unicode character set for naming identifiers was added in Python3. Though, it is not explicitly preferred while writing code, it adds flavour to working with scientific formulas
-11. The original code is [here](https://github.com/python/cpython/blob/master/Lib/antigravity.py) with the [xkcd comic](https://xkcd.com/426/) referenced, and maybe that's why this is also in the `antigravity` module
-12. The [PEP 401](https://www.python.org/dev/peps/pep-0401/) is an April Fools' Joke - The PEP's number is 401, i.e. 4/01 or April 1st (April Fools' Day). The PEP states that Guido van Rossum is stepping down. The new title given to him would be pronounced "BDEVIL" (Benevolent Dictator Emeritus Vacationing Indefinitely from the Language) and Guido's successor will be Barry Warsaw, or as he is affectionately known, Uncle Barry. Uncle Barry's official title is "FLUFL" (Friendly Language Uncle For Life). There are in-jokes about the Parrot virtual machine and the "non-existent" Python Secret Underground (possibly a throw-back to ["TINC" on USENET](https://en.wikipedia.org/wiki/There_Is_No_Cabal)).
