I found the answer!
You can use "/li[1]" at the end for picking the first item on the list.
If you want the second item, then it would be "/li[2]" and so forth.
My example:
search = driver.find_element_by_xpath("//ul[@class='Polaris-ResourceList_r589e']/li[" + str(variant[x]) + "]").click()
In this example, I am using a variable for the #, but if it's static for you, and you only need to get the 2nd item on the list, then it would be this:
search = driver.find_element_by_xpath("//ul[@class='Polaris-ResourceList_r589e']/li[2]").click()
