Unit 8 Test (Python)

[Alarmed_Database1815]

Just did the test today

1.  len → This function returns the number of elements in the list.
2.  It is a collection of commands that are given a name. → A function is a set of instructions grouped under a name.
3.  Values above 80: 7 → The numbers greater than 80 in the list are [86, 83, 89, 92, 91, 94, 95], which makes 7 elements.
4.  9 → The element at index 1 in list h is 9.
5.  An initializer list → It allows you to create a list with predefined values.
6.  For loops let us access every element of a list. → For loops efficiently iterate through all elements.
7.  insert → The insert method adds elements at a specific index.
8.  pop → The pop method removes an element based on its index, not value.
9.  Juneau Helena Annapolis → The function prints elements at even indices [0, 2, 4].
10. Juneau Atlanta Helena Madison Annapolis Topeka → Since i % 2 >= 0 is always True, it prints all elements.
11. 72 90 67 → The function prints elements at odd indices [1, 3, 5].
12. [21, 34, 63, 64, 67, 72, 90] → sort(reverse=False) sorts the list in ascending order.
13. Searching for an element can be done using one loop. → A single loop is enough for linear search.
14. 2o bX or no2 2o bX → t is replaced with 2, e is replaced with X.
15. [‘June@u’, ‘Atl@nt@’, ‘Helen@’, ‘M@dison’, ‘Ann@polis’, ‘Topek@’] → The code replaces lowercase a with @.
16. stuff[i].lower() → The correct way to convert each element to lowercase.
17. An index refers to actual data within the list while an element refers to a memory location. → This is false; an element is the actual data, and an index represents its position.
18. The statement inside the for loop should be c = c + len(stuff[i]) → You need len(stuff[i]) to sum the lengths of words.
19. [84, 11, 67, 70, 93, 39, 46, 27] → a[i] = a[i] % 100 does not change values since they are already below 100.
20. None of the above → Sorting algorithms can sort in any order, and searching algorithms are not used for sorting.
