do need include errno.h if don't access errno directly? eg. void *mem = malloc(16384); if (mem == null) { perror("malloc"); exit(exit_failure); } i tried simple piece of code without including errno.h , worked, i'm not sure if it's ok this. maybe errho.h included in other libraries stdlib.h , don't need explicitly include myself? you don't need <errno.h> if use perror() . from linux programmer's manual : name perror - print system error message synopsis #include <stdio.h> void perror(const char *s); #include <errno.h> const char *sys_errlist[]; int sys_nerr; int errno; this means need <errno.h> if use sys_errlist , sys_nerr or errno . note sys_errlist , sys_nerr bsd extensions. similar entries can found on c99 standard. 7.19.10.4 perror function synopsis #include <stdio.h> void perror(const char *s); and need ...

suppose have list of different types: i.e. [7, 'string 1', 'string 2', [a, b c], 'string 3', 0, (1, 2, 3)] is there pythonic way return 'string 3' ? if have given type, can use several kinds of comprehensions need. [el el in lst if isinstance(el, given_type)][-1] # gives last element if there one, else indexerror or next((el el in reversed(lst) if isinstance(el, given_type)), none) # gives last element if there one, else none if you're doing enough, can factor function: def get_last_of_type(type_, iterable): el in reversed(iterable): if isinstance(el, type_): return el return none

i've defined function in views.py this def ma_fonction_bokeh(request, numero = none): cdr_common = settings.dbcon[settings.mongo_cdrstats['cdr_common']] acc = cdr_common.find() donnees = [] # on initialise une liste in acc: if i['accountcode'] == numero: donnees.append([calendar.timegm(i["start_uepoch"].timetuple()), i["duration"]]) data = simplejson.dumps(donnees) return render(request,"frontend/mongraphe.html", {"name": numero, "data": data}) then in mongraphe.html file i've created javascript code plot got http://www.highcharts.com/stock/demo/dynamic-update want customize plot own data returned function defined @ first... how can that? i've tried ajax function without result you can transfer data python code javascript in several ways. the "proper" way create endpoint returns json data , use ajax request (for example, jquery.getjs...

i'm using corrplot function in seaborn , works flawlessly. however, want little filtering on data. there way hide correlations below or above value? have large data frame , want see correlations greater arbitrary number, .4. i'd 'squares' in image not greater .4 set white, grey or other color. i'm not sure how because corrplot takes full data frame , calculates correlations internally. don't want filter on data frame values, resulting correlation values. maybe there's way resulting image underlying matshow call own code , replot filtering image itself?
