[Tutor] click() performs unreliably
I am trying to click on one of two buttons on a page. Here is an image of
the relevant portion of the page, the HTML and the two xpaths.
/html/body/div[3]/div/div[3]/div[6]/div/div[2]/div/div[3]/a[1]
/html/body/div[3]/div/div[3]/div[6]/div/div[2]/div/div[3]/a[2]
I have made numerous attempts to click on the first button with very limited
success - it works maybe 25% of the time. Looking through the code snippet
below, you will be able to see some of the various techniques I have tried -
I commented out some of the attempts when they failed so that I could
remember what I have tried. I have looked extensively online at previous
posts, but can't find anything that works reliably. The code executes fine
and I can see the button depressed and get routed to the previous page, but
the other actions associated with the click (backing out the previous step)
are not performed. Yet if I pause the code and intervene by clicking on the
button by hand, the routing takes place and the associated steps are
executed. When I click on the second button (with a virtually identical
xpath address) the processing works as it should.
I have tried to find the element by xpath and class name, I have tried
commands with a click() at the end of the find, I have tried
.send_keys("\n") at the end of the find and other approaches as well. A
simple find_element_by_xpath with the address for the second button works
100% of the time. I really don't understand what I am missing and can't seem
to find another method to try. Thanks for any and all thoughts.
##br.get('chrome://settings/')
##
br.execute_script('chrome.settingsPrivate.setDefaultZoom(1.5);')
br.find_element_by_xpath("/html/body/div[3]/div/div[3]/div[6]/div/div[2]/div
/div[3]/a[1]").click()
#br.find_element_by_class_name("go_back_button").send_keys("\n")
# Back out time (test mode)
#print(thread, "Test mode - backing out time(s)")
#result = xpath_search(self, xpath_for_go_back_button, br, 10,
do_click)
##
##button =
br.find_element_by_xpath("//*[@id='main']/div[6]/div/div[2]/div/div[3]/a[1]"
)
##button.click()
###sleep(20)
##result =
xpath_search(self,"/html/body/div[3]/div/div[3]/div[6]/div/div[2]/div/div[3]
/a[1]", br, 5, do_click)
##print("Back out time result =", result)
##if result == failure:
##self.queue.put("(" + thread + ") Unable to back out time")
##if thread == "1":
##endApplication(self, br, thread)
return
##try:
##WebDriverWait(br,
5).until(EC.element_to_be_clickable((By.XPATH, xpath_for_go_back_button)))
##back_out =
br.find_element_by_xpath(xpath_for_go_back_button)
##back_out.click()
##print("Cancel tee time worked")
##except NoSuchElementException:
##print("Cancel tee time did not work")
##return

I assume this is related to your earlier post about using Selenium? If so, you will probably get a better response asking on the Selenium help fora since this list is really focused on core Python and the standard library. Relatively few members will be using Selenium. The Selenium support pages has several suggestions: https://www.seleniumhq.org/support/ -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

If so, then also worth looking at the pipfile and pipenv which are aiming to improve on the experience. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] A retired question
After saying I dropped my request, short replies keep coming. Let me reply in this context: Would there be BUILT-IN tools that can be expected to already be everywhere which can be used at the top of a program you write and distribute to quickly check if the rest of the program has the resources it needs to run probably. I am not currently planning on designing or implementing anything. It was an academic question. I was thinking along the lines of slightly advanced ways functions can start with a group of assertions testing what is expected and quit if not set right. They use assert(). Some of what is being suggested may have useful pieces you can use in doing something like this. But I note that the ability to package things is not something most users need. You need a kernel of guaranteed software you can count on in order to test if other required elements and conditions can be met. Realistically, there are so many variations on python and how you can get copies distributed that I cannot assume that if I write a routine that uses numpy or pandas, as I have been doing, will be installed before a user makes use of the software. And, you can even build your own versions of python while leaving out or including things. It is nice to be flexible. But then you may need to stock to some version from prehistoric times using relatively few features AND being careful to not use features that were later changed or removed. Why bother? OK, here is the solution. At the beginning of the script put out a big warning telling the user that if they do not have all the required software they are proceeding at their own risk and take full responsibility if something weird happens before the software dies. Hitting ENTER will be considered acceptance of the terms! Again. Dropped. Moving on. If the goal here is to tutor, no need to share complex solutions but rather help students learn how to look at their problems and see what kinds of data and logic to apply in what order and then how to debug the inevitable mistakes like a missing comma. -Original Message- From: Tutor On Behalf Of Mats Wichmann Sent: Monday, November 26, 2018 10:23 AM To: paso...@gmail.com Cc: tutor@python.org Subject: Re: [Tutor] A required question On 11/25/18 8:54 PM, Asokan Pichai wrote: > On Sat, Nov 24, 2018, 14:33 Avi Gross >> David, >> >> As I suspected.

But the whole idea of the Python "batteries included" concept is that Python + standard library gets you an impressively long way without resorting to external modules, and that set is a promise. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
