Unable to click expand button using selenium web driver in Python - python-3.x

Question

I'm totally new to programming. Currently trying to automate few daily tasks using selenium web driver on Python. I have a webpage which contains multiple + expand button. Below is the code
Without expansion:
<div class="expansion container">
<div class="expansion_base_parent"></div>
<div class="expansion expansion_parent">
<button type="button" class="compact-visual-toggle"></button>
</div>
</div>
With expansion
<div class="expansion_container">
<div class="expansion_base_parent"></div>
<div class="expansion expansion_parent">
<button type="button" class="compact-visual-toggle active"></button>
</div>
</div>
I'm unable to find this element using any of the find_by method
My colleague said the page contains json that's why unable to locate using find_by
Can somebody please help with the code to locate and click the expand button.
Actual page:
Go-to https://fortigate.fortidemo.com
Username demo
Password demo
Click login read-only
Click later in next window
Now navigate to Network > interfaces There you can see lot of expand button that's what I'm referring I have written code to come till this page, but I want to expand before taking screenshot of the page

Answer 1

It does not have to do anything with JSON.
See, you are saying
<div class="expansion container">
<div class="expansion_base_parent"></div>
<div class="expansion expansion_parent">
<button type="button" class="compact-visual-toggle"></button>
</div>
</div>
that you see this HTML when expand button is present.
You can locate with below css :-
button.compact-visual-toggle
or xpath :
//button[contains(#class, 'compact-visual-toggle')]
and since you have mentioned that they are multiple expension button, you can differentiate like below :
(//button[contains(#class, 'compact-visual-toggle')])[1]
should represent the first, for second you can try :
(//button[contains(#class, 'compact-visual-toggle')])[2]
and so on.. for 3rd, 4th....
in code you can use it like this :
driver.find_element_by_xpath("//button[contains(#class, 'compact-visual-toggle')]").click()
or
driver.find_element_by_xpath("(//button[contains(#class, 'compact-visual-toggle')])[1]").click()
or
driver.find_element_by_xpath("(//button[contains(#class, 'compact-visual-toggle')])[2]").click()
Now, coming to second part :
<div class="expansion_container">
<div class="expansion_base_parent"></div>
<div class="expansion expansion_parent">
<button type="button" class="compact-visual-toggle active"></button>
</div>
</div>
in you you want to un-expand it, you could use the below xpath :
//button[contains(#class, 'compact-visual-toggle active')]
and use it like above.
