True.

Go back to Question 15

False. The output is shown in Figure 15 . The first string in myList in Figure 14 did not match the re pattern. Therefore, it did not appear in the output.

Figure 15 . Answer 14.
Dick TomDickHarry Dick is my name

Go back to Question 14

Answer 13

True. Note the similarity between the code in this question and the code in Question 11 and Question 12. The lambda function was used in those earlier questions simply to show how to use regular expressions with a lambda function. This will be important for use with the filter function later.

Go back to Question 13

Answer 12

False. The output is shown in Figure 12 . Note the difference in the behavior of the search and match functions of the re module.

Figure 12 . Answer 12.
