a live object to which methods can be dispatched synchronously. Broken
promises are incapable of invoking methods: they all result in Failure.

r"""
Evaluates the secondary zeta function `Z(s)`, defined for
`\mathrm{Re}(s)>1` by
.. math ::
Z(s) = \sum_{n=1}^{\infty} \frac{1}{\tau_n^s}
where `\frac12+i\tau_n` runs through the zeros of `\zeta(s)` with
imaginary part positive.
`Z(s)` extends to a meromorphic function on `\mathbb{C}` with a
double pole at `s=1` and simple poles at the points `-2n` for
`n=0`, 1, 2, ...
**Examples**
>>> from mpmath import *
>>> mp.pretty = True; mp.dps = 15
>>> secondzeta(2)
0.023104993115419
>>> xi = lambda s: 0.5*s*(s-1)*pi**(-0.5*s)*gamma(0.5*s)*zeta(s)
>>> Xi = lambda t: xi(0.5+t*j)
>>> -0.5*diff(Xi,0,n=2)/Xi(0)
(0.023104993115419 + 0.0j)
We may ask for an approximate error value::
>>> secondzeta(0.5+100j, error=True)
((-0.216272011276718 - 0.844952708937228j), 2.22044604925031e-16)
The function has poles at the negative odd integers,
and dyadic rational values at the negative even integers::
>>> mp.dps = 30
>>> secondzeta(-8)
-0.67236328125
>>> secondzeta(-7)
+inf
**Implementation notes**
The function is computed as sum of four terms `Z(s)=A(s)-P(s)+E(s)-S(s)`
respectively main, prime, exponential and singular terms.
The main term `A(s)` is computed from the zeros of zeta.
The prime term depends on the von Mangoldt function.
The singular term is responsible for the poles of the function.
The four terms depends on a small parameter `a`. We may change the
value of `a`. Theoretically this has no effect on the sum of the four
terms, but in practice may be important.
A smaller value of the parameter `a` makes `A(s)` depend on
a smaller number of zeros of zeta, but `P(s)` uses more values of
von Mangoldt function.
We may also add a verbose option to obtain data about the
values of the four terms.
>>> mp.dps = 10

Notice the great cancellation between the four terms. Changing `a`, the
four terms are very different numbers but the cancellation gives
the good value of Z(s).

r"""
Gives the Lerch transcendent, defined for `|z| < 1` and
`\Re{a} > 0` by
.. math ::
\Phi(z,s,a) = \sum_{k=0}^{\infty} \frac{z^k}{(a+k)^s}
and generally by the recurrence `\Phi(z,s,a) = z \Phi(z,s,a+1) + a^{-s}`
along with the integral representation valid for `\Re{a} > 0`
.. math ::
\Phi(z,s,a) = \frac{1}{2 a^s} +
\int_0^{\infty} \frac{z^t}{(a+t)^s} dt -
2 \int_0^{\infty} \frac{\sin(t \log z - s
\operatorname{arctan}(t/a)}{(a^2 + t^2)^{s/2}
(e^{2 \pi t}-1)} dt.
The Lerch transcendent generalizes the Hurwitz zeta function :func:`zeta`
(`z = 1`) and the polylogarithm :func:`polylog` (`a = 1`).
**Examples**
Several evaluations in terms of simpler functions::
>>> from mpmath import *
>>> mp.dps = 25; mp.pretty = True
>>> lerchphi(-1,2,0.5); 4*catalan
3.663862376708876060218414
3.663862376708876060218414
>>> diff(lerchphi, (-1,-2,1), (0,1,0)); 7*zeta(3)/(4*pi**2)
0.2131391994087528954617607
0.2131391994087528954617607
>>> lerchphi(-4,1,1); log(5)/4
0.4023594781085250936501898
0.4023594781085250936501898
>>> lerchphi(-3+2j,1,0.5); 2*atanh(sqrt(-3+2j))/sqrt(-3+2j)
(1.142423447120257137774002 + 0.2118232380980201350495795j)
(1.142423447120257137774002 + 0.2118232380980201350495795j)
Evaluation works for complex arguments and `|z| \ge 1`::
>>> lerchphi(1+2j, 3-j, 4+2j)
(0.002025009957009908600539469 + 0.003327897536813558807438089j)
>>> lerchphi(-2,2,-2.5)
-12.28676272353094275265944
>>> lerchphi(10,10,10)
(-4.462130727102185701817349e-11 + 1.575172198981096218823481e-12j)
>>> lerchphi(10,10,-10.5)
(112658784011940.5605789002 + 498113185.5756221777743631j)

short_description: Collect facts from devices running Extreme EXOS
description:
- Collects a base set of device facts from a remote device that
is running EXOS. This module prepends all of the base network
fact keys with C(ansible_net_<fact>). The facts module will
always collect a base set of facts from the device and can
enable or disable collection of additional facts.

- Tested against EXOS 22.5.1.7
options:

description:
- When supplied, this argument will restrict the facts collected
to a given subset. Possible values for this argument include
all, hardware, config, and interfaces. Can specify a list of
values to include a larger subset. Values can also be used
with an initial C(M(!)) to specify that a specific subset should
not be collected.

application = web.Application([
(r"/", MainPageHandler),

http_server = httpserver.HTTPServer(application)
http_server.listen(8080)
ioloop.IOLoop.instance().start()
The constructor for this class takes in a list of URLSpec objects
or (regexp, request_class) tuples. When we receive requests, we
iterate over the list in order and instantiate an instance of the
first request class whose regexp matches the request path.
Each tuple can contain an optional third element, which should be a
dictionary if it is present. That dictionary is passed as keyword
arguments to the contructor of the handler. This pattern is used
for the StaticFileHandler below:
application = web.Application([
(r"/static/(.*)", web.StaticFileHandler, {"path": "/var/www"}),
])
We support virtual hosts with the add_handlers method, which takes in
a host regular expression as the first argument:
application.add_handlers(r"www\.myhost\.com", [
(r"/article/([0-9]+)", ArticleHandler),
])
You can serve static files by sending the static_path setting as a
keyword argument. We will serve those files from the /static/ URI
(this is configurable with the static_url_prefix setting),
and we will serve /favicon.ico and /robots.txt from the same directory.

Given a set of candidate numbers (C) and a target number (T), find all unique combinations in C where the candidate numbers sums to T.
The same repeated number may be chosen from C unlimited number of times.
Note:
All numbers (including target) will be positive integers.
Elements in a combination (a1, a2, … , ak) must be in non-descending order. (ie, a1 ≤ a2 ≤ … ≤ ak).
The solution set must not contain duplicate combinations.
For example, given candidate set 2,3,6,7 and target 7,
A solution set is:
[7]
[2, 2, 3]
class Solution:
# @param candidates, a list of integers
# @param target, integer
# @return a list of lists of integers
# Recursion
# Sort the array at first, then use the recursion to find
# the result, Time O(n^2)
# 96ms

self.dfs(candidates,target,0,[])
return self.result
def dfs(self,candidates,target,start,reslist):

for i in xrange(len(can)):
if not res or res[len(res)-1] <= can[i]:
self.dfs(can,cursum+can[i],target,res+[can[i]])
For the combination_sum2, just change the start index from i to the i+1
Time Complexity: T(n) = T(n-1) + 1 = O(n) ？

Parameters
----------

phi_list : array of feature functions (default: [`manual_content_flags`])
Any function that takes a string as input and returns a

class_func : function on the labels
A function that modifies the labels based on the experimental
design. If `class_func` returns None for a label, then that
item is ignored.
vectorizer : sklearn.feature_extraction.DictVectorizer
If this is None, then a new `DictVectorizer` is created and
used to turn the list of dicts created by `phi` into a
feature matrix. This happens when we are training.
If this is not None, then it's assumed to be a `DictVectorizer`

assessment, when we take in new instances and need to
featurize them as we did in training.

Iterator for training data.
assess_reader : iterator or None (default: None)
If None, then the data from `train_reader` are split into
a random train/test split, with the the train percentage
determined by `train_size`. If not None, then this should
be an iterator for assessment data (e.g., `dev_reader`).

Any function that takes a feature matrix and a label list

function that operates on feature matrices.
score_metric : function name (default: `utils.safe_weighted_f1`)
This should be an `sklearn.metrics` scoring function. The
default is weighted average F1.
verbose : bool (default: True)
Whether to print out the model assessment to standard output.

-------

force option is used, the image will either be pulled, built or loaded. By default the image will be pulled
from Docker Hub. To build the image, provide a path value set to a directory containing a context and
Dockerfile. To load an image, specify load_path to provide a path to an archive file. To tag an image to a
repository, provide a repository path. If the name contains a repository path, it will be pushed.
