class Extension:
"""Just a collection of attributes that describes an extension
module and everything needed to build it (hopefully in a portable
way, but there are hooks that let you be as unportable as you need).
Instance attributes:
name : string
the full name of the extension, including any packages -- ie.
*not* a filename or pathname, but Python dotted name
sources : [string]
list of source filenames, relative to the distribution root
(where the setup script lives), in Unix form (slash-separated)
for portability. Source files may be C, C++, SWIG (.i),
platform-specific resource files, or whatever else is recognized
by the "build_ext" command as source for a Python extension.
include_dirs : [string]
list of directories to search for C/C++ header files (in Unix
form for portability)
define_macros : [(name : string, value : string|None)]
list of macros to define; each macro is defined using a 2-tuple,
where 'value' is either the string to define it to or None to
define it without a particular value (equivalent of "#define
FOO" in source or -DFOO on Unix C compiler command line)
undef_macros : [string]
list of macros to undefine explicitly
library_dirs : [string]
list of directories to search for C/C++ libraries at link time
libraries : [string]
list of library names (not filenames or paths) to link against
runtime_library_dirs : [string]
list of directories to search for C/C++ libraries at run time
(for shared extensions, this is when the extension is loaded)
extra_objects : [string]
list of extra files to link with (eg. object files not implied
by 'sources', static library that must be explicitly specified,
binary resource files, etc.)
extra_compile_args : [string]
any extra platform- and compiler-specific information to use
when compiling the source files in 'sources'. For platforms and
compilers where "command line" makes sense, this is typically a
list of command-line arguments, but for other platforms it could
be anything.
extra_link_args : [string]
any extra platform- and compiler-specific information to use
when linking object files together to create the extension (or
to create a new static Python interpreter). Similar
interpretation as for 'extra_compile_args'.
export_symbols : [string]
list of symbols to be exported from a shared extension. Not
used on all platforms, and not generally necessary for Python
extensions, which typically export exactly one symbol: "init" +
extension_name.
swig_opts : [string]
any extra options to pass to SWIG if a source file has the .i
extension.
depends : [string]
list of files that the extension depends on
language : string
extension language (i.e. "c", "c++", "objc"). Will be detected
from the source extensions if not provided.

r"""A fast and complete Python implementation of Markdown.
[from http://daringfireball.net/projects/markdown/]
> Markdown is a text-to-HTML filter; it translates an easy-to-read /
> easy-to-write structured text format into HTML. Markdown's text
> format is most similar to that of plain text email, and supports
> features such as headers, *emphasis*, code blocks, blockquotes, and
> links.
>
> Markdown's syntax is designed not as a generic markup language, but
> specifically to serve as a front-end to (X)HTML. You can use span-level
> HTML tags anywhere in a Markdown document, and you can use block level
> HTML tags (like <div> and <table> as well).
Module usage:
>>> import markdown2
>>> markdown2.markdown("*boo!*") # or use `html = markdown_path(PATH)`
u'<p><em>boo!</em></p>\n'
>>> markdowner = Markdown()
>>> markdowner.convert("*boo!*")
u'<p><em>boo!</em></p>\n'
>>> markdowner.convert("**boom!**")
u'<p><strong>boom!</strong></p>\n'
This implementation of Markdown implements the full "core" syntax plus a
number of extras (e.g., code syntax coloring, footnotes) as described on
<https://github.com/trentm/python-markdown2/wiki/Extras>.
"""
cmdln_desc = """A fast and complete Python implementation of Markdown, a
text-to-HTML conversion tool for web writers.
Supported extra syntax options (see -x|--extras option below and
see <https://github.com/trentm/python-markdown2/wiki/Extras> for details):
* code-friendly: Disable _ and __ for em and strong.
* cuddled-lists: Allow lists to be cuddled to the preceding paragraph.
* fenced-code-blocks: Allows a code block to not have to be indented
by fencing it with '```' on a line before and after. Based on
<http://github.github.com/github-flavored-markdown/> with support for
syntax highlighting.
* footnotes: Support footnotes as in use on daringfireball.net and
implemented in other Markdown processors (tho not in Markdown.pl v1.0.1).
* header-ids: Adds "id" attributes to headers. The id value is a slug of
the header text.
* html-classes: Takes a dict mapping html tag names (lowercase) to a
string to use for a "class" tag attribute. Currently only supports
"pre" and "code" tags. Add an issue if you require this for other tags.
* markdown-in-html: Allow the use of `markdown="1"` in a block HTML tag to
have markdown processing be done on its contents. Similar to
<http://michelf.com/projects/php-markdown/extra/#markdown-attr> but with
some limitations.
* metadata: Extract metadata from a leading '---'-fenced block.
See <https://github.com/trentm/python-markdown2/issues/77> for details.
* nofollow: Add `rel="nofollow"` to add `<a>` tags with an href. See
<http://en.wikipedia.org/wiki/Nofollow>.
* pyshell: Treats unindented Python interactive shell sessions as <code>
blocks.
* link-patterns: Auto-link given regex patterns in text (e.g. bug number
references, revision number references).
* smarty-pants: Replaces ' and " with curly quotation marks or curly
apostrophes. Replaces --, ---, ..., and . . . with en dashes, em dashes,
and ellipses.
* toc: The returned HTML string gets a new "toc_html" attribute which is
a Table of Contents for the document. (experimental)
* xml: Passes one-liner processing instructions and namespaced XML tags.
* tables: Tables using the same format as GFM
<https://help.github.com/articles/github-flavored-markdown#tables> and
PHP-Markdown Extra <https://michelf.ca/projects/php-markdown/extra/#table>.
* wiki-tables: Google Code Wiki-style tables. See
<http://code.google.com/p/support/wiki/WikiSyntax#Tables>.

Class for `NodeCollection`.
`NodeCollection` represents the nodes of a network. The class supports
iteration, concatenation, indexing, slicing, membership, length, conversion to and
from lists, test for membership, and test for equality. By using the
membership functions :py:func:`get()` and :py:func:`set()`, you can get and set desired
parameters.
A `NodeCollection` is created by the :py:func:`.Create` function, or by converting a
list of nodes to a `NodeCollection` with ``nest.NodeCollection(list)``.
If your nodes have spatial extent, use the member parameter ``spatial`` to get the spatial information.
Example
-------
::

Inverse radon transform.
Reconstruct an image from the radon transform, using the filtered

Parameters
----------
radon_image : array_like, dtype=float
Image containing radon transform (sinogram). Each column of
the image corresponds to a projection along a different angle. The
tomography rotation axis should lie at the pixel index
``radon_image.shape[0] // 2`` along the 0th dimension of
``radon_image``.

Reconstruction angles (in degrees). Default: m angles evenly spaced
between 0 and 180 (if the shape of `radon_image` is (N, M)).
output_size : int
Number of rows and columns in the reconstruction.
workspace : ``None`` or result of ``iradon_workspace()``
Workspace is a tuple of arrays with values needed for iradon
transform, as calculated by ``iradon_workspace(theta, output_size)``.
If ``None`` (default), the work arrays are generated as needed.
filter : str, optional (default ramp)
Filter used in frequency domain filtering. Ramp filter used by default.
Filters available: ramp, shepp-logan, cosine, hamming, hann.
Assign None to use no filter.
interpolation : str, optional (default 'linear')
Interpolation method used in reconstruction. Methods available:
'linear', 'nearest', and 'cubic' ('cubic' is slow).
circle : boolean, optional
Assume the reconstructed image is zero outside the inscribed circle.
Also changes the default output_size to match the behaviour of
``radon`` called with ``circle=True``.
Returns
-------
reconstructed : ndarray
Reconstructed image. The rotation axis will be located in the pixel
with indices
``(reconstructed.shape[0] // 2, reconstructed.shape[1] // 2)``.
Notes
-----
It applies the Fourier slice theorem to reconstruct an image by
multiplying the frequency domain of the filter with the FFT of the
projection data. This algorithm is called filtered back projection.

Inverse radon transform
Reconstruct an image from the radon transform, using a single iteration of
the Simultaneous Algebraic Reconstruction Technique (SART) algorithm.
Parameters
----------
radon_image : 2D array, dtype=float
Image containing radon transform (sinogram). Each column of
the image corresponds to a projection along a different angle. The
tomography rotation axis should lie at the pixel index
``radon_image.shape[0] // 2`` along the 0th dimension of
``radon_image``.
theta : 1D array, dtype=float, optional
Reconstruction angles (in degrees). Default: m angles evenly spaced
between 0 and 180 (if the shape of `radon_image` is (N, M)).
image : 2D array, dtype=float, optional
Image containing an initial reconstruction estimate. Shape of this
array should be ``(radon_image.shape[0], radon_image.shape[0])``. The
default is an array of zeros.
projection_shifts : 1D array, dtype=float
Shift the projections contained in ``radon_image`` (the sinogram) by
this many pixels before reconstructing the image. The i'th value
defines the shift of the i'th column of ``radon_image``.
clip : length-2 sequence of floats
Force all values in the reconstructed tomogram to lie in the range
``[clip[0], clip[1]]``
relaxation : float
Relaxation parameter for the update step. A higher value can
improve the convergence rate, but one runs the risk of instabilities.
Values close to or higher than 1 are not recommended.
Returns
-------
reconstructed : ndarray
Reconstructed image. The rotation axis will be located in the pixel
with indices
``(reconstructed.shape[0] // 2, reconstructed.shape[1] // 2)``.
Notes
-----
Algebraic Reconstruction Techniques are based on formulating the tomography
reconstruction problem as a set of linear equations. Along each ray,
the projected value is the sum of all the values of the cross section along
the ray. A typical feature of SART (and a few other variants of algebraic
techniques) is that it samples the cross section at equidistant points
along the ray, using linear interpolation between the pixel values of the
cross section. The resulting set of linear equations are then solved using
a slightly modified Kaczmarz method.
When using SART, a single iteration is usually sufficient to obtain a good
reconstruction. Further iterations will tend to enhance high-frequency
information, but will also often increase the noise.

Robust grading allows student scores to be saved per-subsection independent

We also persist students' course-level grades, and update them whenever
a student's score or the course grading policy changes. As they are

The ``distro`` package (``distro`` stands for Linux Distribution) provides
information about the Linux distribution it runs on, such as a reliable
machine-readable distro ID, or version information.
It is a renewed alternative implementation for Python's original
:py:func:`platform.linux_distribution` function, but it provides much more
functionality. An alternative implementation became necessary because Python
3.5 deprecated this function, and Python 3.7 is expected to remove it
altogether. Its predecessor function :py:func:`platform.dist` was already
deprecated since Python 2.6 and is also expected to be removed in Python 3.7.
Still, there are many cases in which access to Linux distribution information
is needed. See `Python issue 1322 <https://bugs.python.org/issue1322>`_ for
more information.

This package maintains the following reliable distro ID values:
============== =========================================
Distro ID Distribution
============== =========================================
"ubuntu" Ubuntu
"debian" Debian
"rhel" RedHat Enterprise Linux
"centos" CentOS
"fedora" Fedora
"sles" SUSE Linux Enterprise Server
"opensuse" openSUSE
"amazon" Amazon Linux
"arch" Arch Linux
"cloudlinux" CloudLinux OS
"exherbo" Exherbo Linux
"gentoo" GenToo Linux
"ibm_powerkvm" IBM PowerKVM
"kvmibm" KVM for IBM z Systems
"linuxmint" Linux Mint
"mageia" Mageia
"mandriva" Mandriva Linux
"parallels" Parallels
"pidora" Pidora
"raspbian" Raspbian
"oracle" Oracle Linux (and Oracle Enterprise Linux)
"scientific" Scientific Linux
"slackware" Slackware
"xenserver" XenServer
============== =========================================

or if you find that the :func:`distro.id` function returns a different
distro ID for one of the listed distros, please create an issue in the
`distro issue tracker`_.
**Lookup hierarchy and transformations:**
First, the ID is obtained from the following sources, in the specified
order. The first available and non-empty value is used:
* the value of the "ID" attribute of the os-release file,
* the value of the "Distributor ID" attribute returned by the lsb_release
command,
* the first part of the file name of the distro release file,
The so determined ID value then passes the following transformations,
before it is returned by this method:
* it is translated to lower case,
* blanks (which should not be there anyway) are translated to underscores,
* a normalization of the ID is performed, based upon
`normalization tables`_. The purpose of this normalization is to ensure
that the ID is as reliable as possible, even across incompatible changes
in the Linux distributions. A common reason for an incompatible change is
the addition of an os-release file, or the addition of the lsb_release
command, with ID values that differ from what was previously determined
from the distro release file name.
