list? correct answers Names = ["William", "Scott", "Sophia"]
loc = Names.index("Scott")
# loc is 1
Which is an example of using the index method to search for an element from the start
to the end of a list? correct answers List.index(elem, start, end)
T or F: If the index method finds the element, it return its index (position) inside the list.
correct answers True
T or F: A ValueError is given when the index method searches for the element and the
element is not between start and end in the list. correct answers True
T or F: A Searchgive Error is not given when the index method is used and the element
is NOT found. correct answers False
