python - On tkinter, how to determine which of buttons were clicked? -


i'm making big tic-tac-toe game. whenever button pressed, want class gameplay check whether there amount n of same marks in row (=win). can't figure out how tell class gameplay if method move() activated in class box.

sorry, i'm starter. here's code.

from tkinter import *  # grid maxsize = 30*30   def game():     n = [0]     marks = ["x", "o"]     points = [0,0]     boxes = []       class box:         def __init__(self, window, x, y):             self.__x = x             self.__y = y             self.__state = ""             self.__button = button(window, text = self.__state, command = self.move, height = 1, width = 2)         def move(self):             if self.__state == "":                 self.__state = marks[n[0]]                 n[0] = (n[0]+1)%2                 self.__button.config(text = self.__state)          def grid(self, **kwargs):             self.__button.grid(**kwargs)         def state(self):             return self.__state      class gameplay:         def __init__(self, size, towin):             self.__mainwindow = tk()             self.__mainwindow.resizable(width=false, height=false)             self.__mainlabel = label(self.__mainwindow, text = "se, joka saa " + str(towin) + " peräkkäin ensimmäisenä, voittaa!")             self.__mainlabel.grid(row = 0, column = 0, columnspan = size)             boxes = []             y in range(size):                 boxes.append([])                 x in range(size):                     boxes[y].append(box(self.__mainwindow, x, y))                     boxes[y][x].grid(row=y+1, column=x)             self.__mainwindow.mainloop()          playgame = gameplay(20, 4)  game()

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

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
