What is the meaning of the following two images?
These images were inserted here simply to insert some space between the questions and the answers to keep them from being visible on the screen at thesame time.
This image was also inserted for the purpose of inserting space between the questions and the answers.
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
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
False. The output is shown in Figure 12 . Note the difference in the behavior of the search and match functions of the re module.

Matching subString: DickTest string: TomDickHarry
Test string: Dick is my nameMatching subString: Dick |
