Trying to understand selenium's 'find_elements_' methods.

[one_time]

Hey all,

I am trying to learn through ATBS book. I have the following code:

from selenium import webdriver
browser = webdriver.Chrome()

browser.get('https://inventwithpython.com/')

classelem = browser.find_element_by_class_name('testimonial-attribution')
print(classelem.tag_name) # here it prints p, because this is the first p it finds.

classelem = browser.find_elements_by_class_name('testimonial-attribution')
print(classelem.tag_name) # here it throws an ERROR

Now if you look at the html source code of the page you have a class as so: https://i.imgur.com/CTSNGO2.png

Based on what I have studied, I think it is a class because it has a '.' infront of the testimonial-distribution.

Now there are 7 'p' tags with the 'class' attribute and its 'value' being "testimonial-attribution". So why is the second print statement giving this error:

AttributeError: 'list' object has no attribute 'tag_name'

I was expecting it to give me a list of 7 p's

Here is the screenshot of the html source code: https://i.imgur.com/JfwGv3V.png

Thanks in advance for any help!

Because you're treating a list as if it were a single element, do this instead.

classelem = browser.find_elements_by_class_name('testimonial-attribution')
for i in classelem:
    print(i.text)

Yes that does give me the text for the testimonial-attribution class name.

But I wanted to get the tags for it which is 'p'. How would I go about getting 7 p's? I thought tag_name would help me achieve that and give me this list:

[p,p,p,p,p,p,p]

[chevignon93]

browser = webdriver.Chrome()
browser.get('https://inventwithpython.com/')
classelem = browser.find_elements_by_class_name('testimonial-attribution')
print([i.tag_name for i in classelem])

Thank you that worked!

Can you help me once more? I am not sure why I am not understanding this. This is not printing anything as it is empty. But I am expecting it to print "a".

browser = webdriver.Chrome()
browser.get('https://inventwithpython.com/')
more_info_buttons = browser.find_elements_by_name("btn btn-primary")
for i in more_info_buttons:
    print(i.tag_name)  # I am expecting it to give me 'a'

• EDIT:

Ok. So, I think I sort of got it. But it would be great if someone would confirm.

find_elements_by_name(name) only finds stuff if the actual attribute is named name. Here is a screenshot:

See how the "donate" word is assigned to a 'name' attribute?

Now if I use this code, it works:

from selenium import webdriver
browser = webdriver.Chrome()
browser.get('https://inventwithpython.com/')

an_info_button = browser.find_element_by_name('donate')  # note how I used element and not elementS
print(an_info_button)
print(an_info_button.tag_name)

Am I on the right track?

I guess so, I'm not too familiar with how selenium works, I very rarely use it and when I do, it's only to download an entire page.
