3. User clicks activation link, account is now active.
Using this backend requires that
* ``registration`` be listed in the ``INSTALLED_APPS`` setting
(since this backend makes use of models defined in this
application).
* The setting ``ACCOUNT_ACTIVATION_DAYS`` be supplied, specifying
(as an integer) the number of days from registration during
which a user may activate their account (after that period
expires, activation will be disallowed).
* The creation of the templates
``registration/activation_email_subject.txt`` and
``registration/activation_email.txt``, which will be used for
the activation email. See the notes for this backends
``register`` method for details regarding these templates.
Additionally, registration can be temporarily closed by adding the
setting ``REGISTRATION_OPEN`` and setting it to
``False``. Omitting this setting, or setting it to ``True``, will
be interpreted as meaning that registration is currently open and
permitted.
Internally, this is accomplished via storing an activation key in
an instance of ``registration.models.RegistrationProfile``. See
that model and its custom manager for full documentation of its

that group (along with the zero occurrence case from step (1)).
(3) Select the first (essentially an arbitrary) element from any character
class. Select an arbitrary character for any unordered class (e.g. '.'

Contents:
- parse_mime_type(): Parses a mime-type into its component parts.
- parse_media_range(): Media-ranges are mime-types with wild-cards and a 'q' quality parameter.
- quality(): Determines the quality ('q') of a mime-type when compared against a list of media-ranges.
- quality_parsed(): Just like quality() except the second parameter must be pre-parsed.
- best_match(): Choose the mime-type with the highest quality ('q') from a list of candidates.

# Single-Linkage Clustering Algorithm

# This program read the values asociated to the vertices from a file.
# The distance between 2 vertices is calculated with those values.
# For example, if the values are a string of 0s and 1s with a fixed size,
# the hamming distance is the sum of the bits where both strings differ.
# (This is the distance considered in the code but it is easy to change).
#
# Given a positive integer k, the program executes the Single-Linkage
# Clustering Algorithm to find the k clusters that maximize:
# min d(x, y)
# x, y are in a different cluster

# A heap is a representation of a complete binary tree as an array.

# the following equitities are true:
# leftChild(index) = 2*index+1
# rightChild(index) = 2*index+2
# parent(index) = (index-1) // 2
#
# A MinHeap is a heap where there is a total order relation and verifies the following property:
# "heap[i] >= heap[parent(i)] for all i in range(0, size())"
# analogously:
# "Each children is greater or equal than its parent."
#
# Consecuently, heap[0] is the minimum of the elements of the heap.
# A MinHeap supports the following operations:

"""This module defines the core structure of the classification rules.
This module does NOT specify how the rules filter the data: this responsibility
is of to the concrete classifiers, which have to override the Rule class herein
defined and know how to do the math.
This module, instead, defines the format of the rules and the way they are
encoded and loaded (in a python-style dictionary file).
Rules are organized in a tree, where the root is always represented by a 'Total'
node, and the leaves are arbitrarily defined by the user, according to the
following principles:
- Order of siblings rules matter: what is caught by a rule will not be caught
by the next ones, but it is propagated to its children rules if any.
- Every non-leaf node X gets an implicit extra-children named X-other. This
catch-all child catches everything (within the parent rule scope) that is
not caught by the other siblings. This is to guarantee that, when doing the
math (the aggregation), at any level, the sum of the values in the leaves
match the value of their parent.
The format of a rule dictionary is the following:
[
{
'name': 'Name of the rule',
'filter-X': 'The embedder will know how to interpret this value and will use
it to filter the data'
'filter-Y': 'Idem'
children: [
{
'name': 'Name of the sub-rule 1'
... and so on recursively ,
},
]
},
]
And a typical resulting rule tree looks like this:
+----------------------+
| Total |
|----------------------|
+------------------+ Match all. +--------------------+
| +----------+-----------+ |
| | |
+-----v-----+ +-----v-----+ +------v----+
| Foo | | Bar | |Total-other|
|-----------| |-----------| |-----------|
|File: foo* | +---+File: bar* +-----+ | Match all |
+-----------+ | +-----------+ | +-----------+
| |
+------v------+ +------v----+
| Bar::Coffee | | Bar-other |
|-------------| |-----------|

# Purpose:
# The purpose of this script is to convert uses of tests as filters to proper jinja test syntax
# as part of https://github.com/ansible/proposals/issues/83
# Notes:
# This script is imperfect, but was close enough to "fix" all integration tests
# with the exception of:
#
# 1. One file needed manual remediation, where \\\\ was ultimately replace with \\ in 8 locations.
# 2. Multiple filter pipeline is unsupported. Example:
# var|string|search('foo')
# Which should be converted to:
# var|string is search('foo')

Statistical Functions
=====================
This module contains a large number of probability distributions as
well as a growing library of statistical functions.
Each included distribution is an instance of the class rv_continous.
For each given name the following methods are available. See docstring
for rv_continuous for more information
:rvs:
random variates with the distribution
:pdf:
probability density function
:cdf:
cumulative distribution function
:sf:
survival function (1.0 - cdf)
:ppf:
percent-point function (inverse of cdf)
:isf:
inverse survival function
:stats:
mean, variance, and optionally skew and kurtosis
Calling the instance as a function returns a frozen pdf whose shape,
location, and scale parameters are fixed.

A class for writing Stata binary dta files
Parameters
----------
fname : str or buffer
String path of file-like object
data : DataFrame
Input to save
convert_dates : dict
Dictionary mapping columns containing datetime types to stata internal
format to use when wirting the dates. Options are 'tc', 'td', 'tm',
'tw', 'th', 'tq', 'ty'. Column can be either an integer or a name.
Datetime columns that do not have a conversion type specified will be
converted to 'tc'. Raises NotImplementedError if a datetime column has
timezone information

Write the index to Stata dataset.
encoding : str
Default is latin-1. Unicode is not supported
byteorder : str
Can be ">", "<", "little", or "big". default is `sys.byteorder`
time_stamp : datetime
A datetime to use as file creation date. Default is the current time
dataset_label : str
A label for the data set. Must be 80 characters or smaller.
variable_labels : dict
Dictionary containing columns as keys and variable labels as values.
Each label must be 80 characters or smaller.
.. versionadded:: 0.19.0
Returns
-------
writer : StataWriter instance
The StataWriter instance has a write_file method, which will
write the file to the given `fname`.

# Description: Leetcode # 802. Find Eventual Safe States
#
# In a directed graph, we start at some node and every turn,
# walk along a directed edge of the graph.
# If we reach a node that is terminal (that is, it has no outgoing directed edges), we stop.
#
# Now, say our starting node is eventually safe if and only if we must eventually walk to a terminal node.
# More specifically, there exists a natural number K so that for any choice of where to walk,
# we must have stopped at a terminal node in less than K steps.
#
# Which nodes are eventually safe? Return them as an array in sorted order.
#
# The directed graph has N nodes with labels 0, 1, ..., N-1, where N is the length of graph.
# The graph is given in the following form: graph[i] is a list of labels j
# such that (i, j) is a directed edge of the graph.
#
# Example:
# Input: graph = [[1,2],[2,3],[5],[0],[5],[],[]]
# Output: [2,4,5,6]
# Here is a diagram of the above graph.
#
# Illustration of graph
#
# Note:
#
# graph will have length at most 10000.
# The number of edges in the graph will not exceed 32000.
# Each graph[i] will be a sorted list of different integers,
# chosen within the range [0, graph.length - 1].

Volume driver for HP LeftHand Storage array.
This driver requires 11.5 or greater firmware on the LeftHand array, using
the 1.0 or greater version of the hplefthandclient.
You will need to install the python hplefthandclient.
sudo pip install hplefthandclient
Set the following in the cinder.conf file to enable the
LeftHand Channel Driver along with the required flags:
volume_driver=cinder.volume.drivers.san.hp.hp_lefthand_iscsi.
HPLeftHandISCSIDriver
It also requires the setting of hplefthand_api_url, hplefthand_username,
hplefthand_password for credentials to talk to the REST service on the
LeftHand array.

# Special case pip and setuptools to generate versioned wrappers
#
# The issue is that some projects (specifically, pip and setuptools) use
# code in setup.py to create "versioned" entry points - pip2.7 on Python
# 2.7, pip3.3 on Python 3.3, etc. But these entry points are baked into
# the wheel metadata at build time, and so if the wheel is installed with
# a *different* version of Python the entry points will be wrong. The
# correct fix for this is to enhance the metadata to be able to describe
# such versioned entry points, but that won't happen till Metadata 2.0 is
# available.
# In the meantime, projects using versioned entry points will either have
# incorrect versioned entry points, or they will not be able to distribute
# "universal" wheels (i.e., they will need a wheel per Python version).
#
# Because setuptools and pip are bundled with _ensurepip and virtualenv,
# we need to use universal wheels. So, as a stopgap until Metadata 2.0, we
# override the versioned entry points in the wheel and generate the
# correct ones. This code is purely a short-term measure until Metadat 2.0
# is available.
#
# To add the level of hack in this section of code, in order to support
# ensurepip this code will look for an ``ENSUREPIP_OPTIONS`` environment
# variable which will control which version scripts get installed.
#
# ENSUREPIP_OPTIONS=altinstall
# - Only pipX.Y and easy_install-X.Y will be generated and installed
# ENSUREPIP_OPTIONS=install
# - pipX.Y, pipX, easy_install-X.Y will be generated and installed. Note
# that this option is technically if ENSUREPIP_OPTIONS is set and is
# not altinstall
# DEFAULT

Parameters
----------
im_label : array_like
A labeled mask image wherein intensity of a pixel is the ID of the
object it belongs to. Non-zero values are considered to be foreground
objects.
im_intensity : array_like
Intensity image.
num_hist_bins: int, optional
Number of bins used to computed the intensity histogram of an object.
Histogram is used to energy and entropy features. Default is 10.
rprops : output of skimage.measure.regionprops, optional
rprops = skimage.measure.regionprops( im_label ). If rprops is not

This means that user_input from:
"atoms":{"c0": "Br","a0": "test","a1": "(ep)","e10": "H","e11": "(ep)","e20": "H","e21": "(ep)"}}' after parsing to json
is converted to:
{"c0": "Br", "p0": "(ep)", "p1": "test", "p2": "H", "p3": "H", "p4": "(ep)", "p6": "(ep)"}
i.e. aX and eX -> pX
So if converted, p subsets are compared,
if not a and e subsets are compared
If all subsets are equal, grade succeeds.
There is also one special case for AX6 geometry.
In this case user_input["atoms"] contains special 3 symbol keys: e10, e12, e20, and e21.
Correct answer for this geometry can be of 3 types:
1) c0 and peripheral
2) c0 and axial and equatorial
3) c0 and axial and equatorial-subset-1 (e1X) and equatorial-subset-2 (e2X)
If correct answer is type 1 or 2, then user_input is converted from type 3 to type 2 (or to type 1 if convert_to_peripheral is True)
If correct_answer is type 3, then we done special case comparison. We have 3 sets of atoms positions both in user_input and correct_answer: axial, eq-1 and eq-2.
Answer will be correct if these sets are equals for one of permutations. For example, if :
user_axial = correct_eq-1
user_eq-1 = correct-axial
user_eq-2 = correct-eq-2
