Answer the following statement true (T) or false (F)
Which of the following statements is false?
a. Use list method extend to add all the elements of another sequence to the end of a list (this is the equivalent of using +=). b. The following code adds all the characters of a string then all the elements of a tuple to a list: sample_list = [] s = 'abc' sample_list.extend(s) t = (1, 2, 3) sample_list.extend(t) c. Rather than creating a temporary variable, like t, to store a tuple in Part (b) before appending it to a list, you might want to pass a tuple directly to extend. In this case, the tuple’s parentheses are optional, because extend expects one iterable argument. d. All of the above statements are true.
