call definite folder name and value in dictionary in Python -


i want write function copy structure , content of 1 root folder 1 (that contains of files in initial folder , function must compare files , directories , copy if not exists in destination folder). name of folders dict.values(). 

def copy_tran(reg_dir):      z_folders = os.listdir(reg_dir)     png_folder = r'c:\users\tei\desktop\temp'     png_subfolders = os.listdir(png_folder)     dir in z_folders:         pngdir in png_subfolders:             path_dir2 = os.path.join(png_folder, pngdir)              path_dir = os.path.join(reg_dir, dir)             transp_basename = os.path.basename(path_dir)[4:]              png_basename = os.path.basename(path_dir2)[4:]              if transp_basename == png_basename:                 region in dict.values():                     if not os.path.exists(png_folder + '\\' + 'reg_' + ('%s' % (region))):                         os.mkdir(png_folder + '\\' + 'reg_' + ('%s' % (region)))                     list_zooms = ['8', '9', '10', '11']                                        zoom in list_zooms:                         if not os.path.exists(png_folder + '\\' + 'reg_' + ('%s' % (region)) + '\\' + (                                     '%s' % (zoom))):                             os.mkdir(png_folder + '\\' + 'reg_' + ('%s' % (region)) + '\\' + ('%s' % (zoom)))                         x_path = os.path.join(path_dir, zoom)                         list_x = os.listdir(x_path)                         y in list_x:                             y_path = os.path.join(x_path, y)                             if not os.path.exists(png_folder + '\\' + 'reg_' + ('%s' % (region)) + '\\' + (                                 '%s' % (zoom)) + '\\' + y):                                 os.mkdir(png_folder + '\\' + 'reg_' + ('%s' % (region)) + '\\' + ('%s' % (zoom)) + '\\' + y)

my code (image) here (debug)

the problem when comparing folder's names, python takes random (as see) folder in root folder (reg_centrsib_north) although in list (2nd line) second element. so, function creates wrong folders (in destination folder reg_center function create subfolders folder reg_centrsib_north). way need rewrite code calls folders of same name (that dict.values())? i'm puzzled, ideas?

try simple solution problem based on shutil.copy2

def copydir(src, dst, symlinks=false, ignore=none):     if not os.path.exists(dst):         os.makedirs(dst)     item in os.listdir(src):         s = os.path.join(src, item)         d = os.path.join(dst, item)         if os.path.isdir(s):             copydir(s, d, symlinks, ignore)         else:             if not os.path.exists(d) or os.stat(s).st_mtime - os.stat(d).st_mtime > 1:                 shutil.copy2(s, d)

this recursive implementation:

  1. check if destination folder exists, if not create it
  2. loop on every element of source folder
  3. if folder call function on , goto 1
  4. if file check if exists , if modified: based on copy

this should jsut copy not esist or has been modified

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
