[[Brotli]] is a compressed data format developed by Google. It is designed for a high compression ratio, and fast decompression. When used as a web content compression encoding, it uses <code>br</code> in the <code>Accept-Encoding</code> header so that a browser can signal support; this support is present in newer versions of Firefox and Chrome as of early 2016.

While the addition of this format to Firefox/Mozilla was still under discussion, there was a bit of a mini-flap over earlier proposals to use "bro" as the encoding identifier (and file extension for Brotli-compressed files), as this was deemed by some to be [https://bugzilla.mozilla.org/show_bug.cgi?id=366559#c147 misogynistic]. After some debate over <code>bro</code> vs. <code>brotli</code> vs. <code>br</code>, the shorter of these was ultimately adopted.

Brotli files (and network traffic) do not have any magic bytes: the first bytes will have right-most bits from [https://datatracker.ietf.org/doc/html/rfc7932#section-9.1 this table], which could be anything.

H2g2bob: add magic

{{FormatInfo
| formattype=electronic

| extensions= {{ext|rrd}}
}}
'''RRD''', the '''round-robin database''' is a format which stores timeseries data.

It's often used to show recent server status details (load, memory usage, bandwidth usage, etc).

The file is a fixed-size rung-buffer, so it only shows a fixed amount of history.

The magic of this file is "RRD\0" ({{magic|52 52 44 00}}).

'''Whisper''' is a format which stores timeseries data for graphite (software for storing timeseries, normally for system monitoring).

There is one whisper file for each metric recorded. The file is a fixed-size file, in a similar way to [[RRD]] files.

While there is no magic for the file, the first four bytes is "aggregation type": a value between {{magic|00 00 00 01}} and {{magic|00 00 00 05}}.

'''Python''' is a [[Programming Languages|programming language]].

It is one of the possibilities for the P in LAMP (a set of technologies used in many web back-ends, including Linux, Apache, and MySQL, notable for being free, open-source software in contrast to proprietary technologies such as those from Microsoft) along with [[Perl]] and [[PHP]].

Media reports of [http://www.cbc.ca/news/canada/story/2013/08/06/f-exotic-animals-laws-canada.html python-linked deaths] have nothing to do with the safety of this language, honest! Actually, the name of the language was inspired by [[Wikipedia:Monty Python|Monty Python]], not any actual reptile (or even [http://www.youtube.com/watch?v=R4yBv4sSKTw fictional ones]).

A notable feature of Python is its use of whitespace as a syntactically-significant part of its structure; the level of indenting of code blocks actually determines its place structurally, in contrast to most other languages which use explicit items such as curly braces or keywords such as [[Pascal]]'s '''begin''' and '''end''' (though in those languages it is still customary to indent code blocks for readability). Other novel features of Python include native support of complex arithmetic (involving both real and imaginary numbers and sums of them).

The easy learnability of the language is enhanced by the fact that it has a command-line interpreter which lets you type commands from a prompt in immediate mode, much like the old-time [[BASIC]] interpreters on which so many people first learned to program back in the days of the Apple II and Commodore 64. However, any program of significant length is likely to be created in a text editor and saved in files.

Python is often affiliated with [[reStructuredText]] documents. Python comments are often formatted with reStructuredText markup.

Versions 2 and 3 of Python (with various sub-versions of each) are both in wide use, with version 2 still usually being the default version included in Linux/Unix distributions, but version 3 gaining popularity; there are a number of minor syntax differences between the two.

O'Reilly's technical books are famous for having animals on their covers. Their book, ''Programming Python'', has a snake on the cover, logically enough. However, other Python-related books from this publisher have different animals, and, in particular, the introductory book ''Learning Python'' has a rodent. Pythons ''eat'' rodents, so is this trying to imply that the Python community will eat newbies whole?

== File extensions ==

Python has a number of file endings associated with it, including .py, .pyc, .pyo, and .pyd. When people have desired a MIME type for Python code, they run into the fact that no standard has been established, and even the nonstandard types don't seem to have reached any degree of consistency; people have tried ''text/python'', ''text/python3'', ''application/python'', ''text/x-python'', and others.

;.py
: A text file that contains python source code. It is often [[utf-8]] encoded, but it does not have to be.
;.pyc
: Compiled [[bytecode]] of a python source file
;.pyo
: Optimized compiled [[bytecode]]
;.pyd
: A python version of a Windows [[Dynamic-link library (Windows)|.dll]] file
;.whl
: A python wheel which is a package distribution for using a "[[ZIP|ZIP-formated]] archive with a specially formatted filename" <ref>Wheel, Python Package Index https://pypi.python.org/pypi/wheel</ref>

'''Allegro''' is a game programming library. The PACKFILE format is a format containing the game's assets in a way which allegro can read (normally: bitmaps, run-length-encoded sprites, [[Amiga Module]] music files from libdumb).

The magic for this file format is {{magic|slh!}} (compressed) or {{magic|slh.}} (uncompressed).

The allegro library is open source and comes with utility libraries for editing PACKFILEs.

{{FormatInfo

|extensions={{ext|dat}}
}}
'''Allegro''' is a game programming library. The PACKFILE format is a zip-file format containing the game's assets in a way which allegro can read (normally: bitmaps, run-length-encoded sprites, mod music files from libdumb).

The magic for this file format is <tt>slh!</tt> (compressed) or <tt>slh.</tt> (uncompressed).

The allegro library is open source and comes with utility libraries for editing PACKFILEs.

Version 5 of Allegro replaces PACKFILE with standard zip utilities.
