python - Selenium, Get Elements By Xpath - Only grab last 60 elements on page -


i'm having little trouble working out how can specify last 60 elements on page

posts = driver.find_elements_by_xpath("""(//div[@class='hotproductdetails'])""") post in posts:     print(post.text)

this code prints every bit of text within elements on webpage. i'm trying scrape site has 'load more' button on it.

the 'load more' button loads 60 more products, , i'd code grab products. way can stick in loop clicks button, grabs products loads, append pandas dataframe , repeats set number of iterations.

i've been unable code me, , once load more button pressed lot of times, grabbing elements can kill chrome , in turn script.

"(//div[@class='hotproductdetails'])[position() > {} , position() <= {}])".format ((page -1 ) * 50, page * 50)

someone shared code me, crashes me error:

invalid selector: unable locate element xpath expression (//div[@class='hotproductdetails'])[position() > {} , position() <= {}])".format ((page -1 ) * 50, page * 50 because of following error: syntaxerror: failed execute 'evaluate' on 'document': string '(//div[@class='hotproductdetails'])[position() > {} , position() <= {}])".format ((page -1 ) * 50, page * 50' not valid xpath expression.   (session info: chrome=60.0.3112.90)   (driver info: chromedriver=2.31.488763 (092de99f48a300323ecf8c2a4e2e7cab51de5ba8),platform=windows nt 10.0.14393 x86_64)

this first time i've ever had web-scraping project , used selenium (which amazing package, impressed it) , i'm not sure fix it. suspect 'page' code, sits on same webpage gets larger load more products.

i can share website i'm scraping if helps - said first scraping project , company joined. don't know if upset me sharing.

if getting invalid xpath selector wrong. there ")" @ end. below works me

page = 2  xpath_selector = "(//div[@class='hotproductdetails'])[position() > {} , position() <= {}]".format ((page -1 ) * 50, page * 50)

also if want last 60 elements can use below

xpath_selector = "(//div[@class='hotproductdetails'])[position() > last() - 60]"

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
