4. (11 pts) In Section 4.1, the author discusses the slicing operator (:) and how it is used with indexing. Given the following string and the corresponding substring from it, complete the following explanation of how slicing works: hamlet = "To be or not to be" print (hamlet [3:5]) The expression hamlet [3:5] evaluates to the slice of the string hamlet starting at index 3 and ending_before _index_5 In order to obtain a slice that ends at the last character of a string, we must drop the second index Illustrate what the above statement means by extracting the second be from the string hamlet. hamlet[_ -2: ] Write the expression that will extract the substring To be" without explicitly specifying the starting index: hamlet [ As the author shows on page 95, you can apply the slicing operator to lists. Let's use the string's split() function (p. 113) to turn the string into a _ of words (by splitting the characters based on the separating them). Use the slicing operator to extract the first two and the last two values in the list. (You can use print() to check the returned values.) hamlet_words = hamlet.split() hamlet_words [_ _ ] # the first two words hamlet_words [_ ] # the last two words using negative indexing
