Ordering

Questions 1 to 5 of 6

1. 1. What does this program print? ``python words = ['b', 'B', 'ab', 'a'] words.sort() print(words) ``

   ['a', 'ab', 'b', 'B']['B', 'a', 'ab', 'b']['a', 'B', 'ab', 'b']['B', 'ab', 'a', 'b']
2. 2. What does this program print? ``python print('apple' > 'app') print('Zebra' > 'apple') ``

   True, then TrueFalse, then FalseFalse, then TrueTrue, then False
3. 3. True or false: '10' < '9' is True.

   True, because the first characters are 1 (code 49) and 9 (code 57), and 49 is smaller, so the comparison stops thereFalse, because 10 is a bigger number than 9, so the comparison gives False
4. 4. True or false: sorted(['Apple', 'apple']) puts apple before Apple.

   True, because the letter a is the first letter of the alphabet, so lowercase words always come firstFalse, because A is 65 and a is 97, so Apple comes first
5. 5. Which key function sorts a list of names ignoring case, and still gives the same order every time when two names differ only in case?

   sorted(names, key=str.lower), because it ignores letter casesorted(names), because the default sort ignores letter casesorted(names, key=lambda s: (s.lower(), s))sorted(names, key=str.swapcase), because it swaps the case of every letter, so the sort ignores case
