As well as setting my_element to the "0th" element of the list, we also then create a variable called my_other_element which we fill from the value at index 2:
my_list = ["cat", "dog", "horse"]
my_element = my_list[0]
print(my_element)
my_other_element = my_list[2]
print(my_other_element)
When run we see that it prints the zeroth and index-2 elements:
python list.py
