Don't understand why I am receiving SIGKILL on python -


i'm beginner python , i'm trying make code on code challenge website when given list of integers, returns integer closest zero. if there 2 different integers same difference, e.g. 3 , -3, should return none. (however if number repeated, e.g. 3 , 3, doesn't count that)

i've made code seems work on outside python interpeters, inside website gives error of "process exited prematurely sigkill signal."

on external python interpreter seems return integer i'm looking for

def closest(lst):      ans = list(filter(lambda x: abs(0-x) == min([abs(0-i) in set(lst)]), set(lst)))      return ans[0] if len(ans) < 2 else none

is there in code causing inefficiency or website?

i suspect coding website testing function passing large generator lst. when program converts set, loads entirety of input memory. if uses memory, process may killed oom killer.

i think following solution ought work. note iterates on lst , doesn't construct other large data structures; state stack variables c , ans. therefore uses constant amount of memory.

def closest(lst):     (c, ans) = (none, none)     in lst:         if (c none) or (abs(i) < abs(c)):             (c, ans) = (i, i)         elif == -1 * c:             ans = none     return ans

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
