Answers

Answer 15

True.

Go back to Question 15

Answer 14

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.

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

what are astronomy
Issan Reply
Astronomy (from Ancient Greek ἀστρονομία (astronomía) 'science that studies the laws of the stars') is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution.

hi !!! I am new in astronomy.... I have so many questions in mind .... all of scientists of the word they just give opinion only. but they never think true or false ... i respect all of them... I believes whole universe depending on true ...থিউরি

there are many theories regarding this it's on you believe any theory that you think is true ex. eternal inflation theory, oscillation model theory, multiple universe theory the big bang theory etc.

from where on earth could u observe all the stars during the during the course of an year
Karuna Reply
I think it couldn't possible on earth
Nagalakshmi
in this time i don't Know
Michele
is that so. the question was in the end of this chapter
Karuna
in theory, you could see them all from the equator (though over the course of a year, not at pne time). stars are measured in "declination", which is how far N or S of the equator (90* to -90*). Polaris is the North star, and is ALMOST 90* (+89*). So it would just barely creep over the horizon.
