Python - How to transform a list of tuple to a tuple -

-

this question has answer here:

i retrieved data sql query and

i have list of tuple like:

[(34.2424,), (-64.2344,) (76.3534,), (45.2344,)]

and have string (34.2424, -64.2344, 76.3534, 45.2344,)

does function exist can that?

notice ',' @ end of each tuple... have difficulty rid of it

if you're using python 2.x, can use:

>>> = [(34.2424, -64.2344, 76.3534, 45.2344)] >>> print ' '.join(map(str, a[0])) '34.2424 -64.2344 76.3534 45.2344'

in python 3.x, or python 2.x from __future__ import print_function, can use:

>>> print(*a[0]) 34.2424 -64.2344 76.3534 45.2344

you seem have updated format of input data, so:

first element each tuple... 

>>> = [(34.2424,), (-64.2344,), (76.3534,), (45.2344,)] >>> print ' '.join(str(el[0]) el in a) 34.2424 -64.2344 76.3534 45.2344

more 1 element in each tuple...

>>> itertools import chain >>> print(*chain.from_iterable(a)) 34.2424 -64.2344 76.3534 45.2344

however, seem want tuple...

>>> tuple(chain.from_iterable(a)) (34.2424, -64.2344, 76.3534, 45.2344)

which can use str on make str if wanted...

c# - must be a non-abstract type with a public parameterless constructor in redis -

-
when save object, got below error must non-abstract type public parameterless constructor in order use parameter 't' in generic type or method 'servicestack.redis.redisclient.store<t>(t) redisclass.getinstnace().store(msg); // error here redisclass.getinstnace().save(); as third party's class, can not edit how save object? could create wrapper around third party object call constructor, store wrapper? e.g. public class mywrapper { public thirdpartyobject thirdpartyinstance { get; set; } public mywrapper() { thirdpartyinstance = new thirdpartyobject("constructors"); } }

i've embedded microsoft.reporting.webforms.reportviewer control in aspx. site works on mysite.com. when try exmple export report, there new black window opened address mysite.com/reserved.reportviewerwebcontrol.axd... it's working fine. but.. pass axd via proxy. mean, i'd force export use url myproxy.mysite.com/reserved.reportviewerwebcontrol.axd... redirect request mysite.com/reserved.reportviewerwebcontrol.axd... i've noticed, link build within js (that inlcuded in axd): exportreport: function(format) { if (this.exporturlbase == null) return false; window.open(this.exporturlbase + encodeuricomponent(format), "_blank"); return true; }, the url axd stored in exporturlbase . how can change proxy serwer url? it possible modify exporturlbase field in javascript. report stored in placeholder somewhere on page, once found can create call _getinternalviewer() function on gain access exporturlbase. have @ following code: ...

time series - R growth rate calculation week over week on daily timeseries data -

-
i'm trying calculate w/w growth rates entirely in r. use excel, or preprocess ruby, that's not point. data.frame example date gpv type 1 2013-04-01 12900 office 2 2013-04-02 16232 office 3 2013-04-03 10035 office i want factored 'type' , need wrap date type column weeks. , calculate week on week growth. i think need ddply group week - custom function determines if date in given week or not? then, after that, use diff , find growth b/w weeks divided previous week. then i'll plot week/week growths, or use data.frame export it. this closed had same useful ideas. update: answer ggplot: all same below, use instead of plot ggplot(data.frame(week=seq(length(gr)), gr), aes(x=week,y=gr*100)) + geom_point() + geom_smooth(method='loess') + coord_cartesian(xlim = c(.95, 10.05)) + scale_x_discrete() + ggtitle('week on week growth rate, apr 1') + ylab('growth rate %') (old, correct answer using plot) w...
