Selenium-python2.7: click on a modal table checkbox (following Selenium IDE)

Question

I think my question is somehow related to this post Selenium - cannot click on an element inside a modal

I click on a an element and it opens a modal table. Then, I would like to select a particular checknox in a long list but Selenium gives me back an error.

That's what I did:

I tested first with Selenium IDE: first I recorded the operations but when I try to replay them in the log I get this:

Running 'Step2_sele'
1.open on /reserve-space/... OK
2.click on css=a[title="Locations"] > span... OK
3.click on linkText=Add/Remove Locations... OK
4.Trying to find xpath=//input[@value='2427']... Failed:
Element is not currently visible and may not be manipulated

I thought I should have given more time to the element to show up and I wrote this with Python

browser = webdriver.Chrome()
browser.get(url_res)
time.sleep(10)
browser.find_element_by_css_selector('a[title="Locations"]>span').click()
time.sleep(10)
browser.find_element_by_css_selector('a.dynamic-filter-item-add.summary').click()
time.sleep(10)
browser.find_element_by_xpath("xpath=//input[@value='2427']").click()

But I get this other error

Traceback (most recent call last):
  File "bot.py", line 69, in <module>
    browser.find_element_by_xpath("xpath=//input[@value='2427']").click()

This is a screenshot of how the html code look like because I cannot post the real url

Why did you add `"xpath="` to your XPath? What do you think it should do? — Andersson, Oct 04 '18 at 17:56
I'm very new to Selenium and HTML, I think I have done some cut and paste from the wrong example. I don't see any other explanation! — spec3, Oct 04 '18 at 21:31

I assume the xpath string causes the problem. If my assumption is correction, the following should work:

browser.find_element_by_xpath("//input[@value='2427']").click()
