find_elements method return a list of WebElement objects.
These are not links (strings).
WebElement is a reference, a pointer to physical web element on the web page.
WebElement may containg href attribute that normally contains some link.
As mentioned by KunduK anchor elements are normally containing links, not p tag elements.
So, in case elements you collecting are containing links you can extract these links from the WebElement objects and use them later.
I can't debug this code since you did not share a link to page you working on as well as you did not share all your Selenium code, but I guess something like following can work:
links = []
classe = driver.find_elements(By. XPATH, "//*[@class='LinksShowcase_UrlContainer__kMj_n']/p")
for i in classe:
link = i.get_attribute("href")
print(link)
links.append(link)
for linkAtual in links:
driver.get(linkAtual)
UPD
In your case it is not href attribute but a text content. So, you can simply extract the text as following:
links = []
classe = driver.find_elements(By. XPATH, "//*[@class='LinksShowcase_UrlContainer__kMj_n']/p")
for i in classe:
link = i.text
print(link)
links.append(link)
for linkAtual in links:
driver.get(linkAtual)
anchortag withhrefattribute. Please post the relevant HTML or share the page link.
