i'm iterating on list of tuples in python, , attempting remove them if meet criteria. for tup in somelist: if determine(tup): code_to_remove_tup what should use in place of code_to_remove_tup ? can't figure out how remove item in fashion. you can use list comprehension create new list containing elements don't want remove: somelist = [x x in somelist if not determine(x)] or, assigning slice somelist[:] , can mutate existing list contain items want: somelist[:] = [x x in somelist if not determine(x)] this approach useful if there other references somelist need reflect changes. instead of comprehension, use itertools . in python 2: from itertools import ifilterfalse somelist[:] = ifilterfalse(determine, somelist) or in python 3: from itertools import filterfalse somelist[:] = filterfalse(determine, somelist)

i using libcurl multi interface , need know how data being sent each request. rather not use curlopt_xferinfofunction because gets called lot , need know dltotal while in curlopt_writefunction callback. want clean existing easy handle , malloc'd data while still in write callback once data has been received. there function can call return total amount of data being sent particular easy handle? i tried using curl_easy_getinfo() curlinfo_size_download , returned 0 . tried curlinfo_content_length_download returned 0 . calling within curlopt_writefunction callback. the reason zeroes calls because size isn't known before-hand. but let me alert "i want clean existing easy handle , malloc'd data while still in write callback" sounds disaster waiting happen. should not cleanup handle within callback.

i'm using fuelux spinbox 3.7.3 according docs: http://getfuelux.com/javascript.html#spinbox can handle change event through "changed.fu.spinbox". event fires 2 arguments: event , value, being value current value. is possible new value? (or @ least know if increase or decrease). examined both arguments , find reference new value. at time event fired, input still not updated , therefore cannot new value way.. in change event take action depending of increment or decrease. any other approach appreciated thanks the changed.fu.spinbox should return new value. i visited nightly build server fuel ux , if open browser's console, should see change event returns new value, not old value. there bug causes changed event fire twice on first click of spinbox, after new value returned via value parameter of event. i recommend storing old value , comparing new value in order discover increase or decrease.

until today , thought hash keys randomised when returned. however, entry in perldoc on keys suggests otherwise: hash entries returned in apparently random order. actual random order specific given hash; exact same series of operations on 2 hashes may result in different order each hash. there other entries on relate - pertinent accepted answer this question. the following code returns apparently randomised hash keys: %hash; $hash{$_}++ 1 .. 100; keys %hash; can me understand how not actually random? how hash keys sorted depends on version of perl using. should not depend on seeming order associated version. includes assuming somehow randomization involved appropriate used in other circumstances statistical qualities of randomness matters. from 5.18 hash overhaul : hash overhaul changes implementation of hashes in perl v5.18.0 1 of visible changes behavior of existing code. by default, 2 distinct hash variables identical keys , val...
