Question
What is printed by the following code snippet?wordsList=['a']wordsList.append('b')wordsList.append('c')wordsList.pop()wordsList.append('d')wordsList.append('e')print(wordsList[:2])A. [‘a’,’b’]B. [‘b’,’c’]C. [‘d’,’e’]D. [‘c’,’d’]E. None of the above
Solution
The code snippet works as follows:
- A list called
wordsListis created with one element: 'a'. - 'b' is appended to the end of
wordsList. - 'c' is appended to the end of
wordsList. - The
pop()function is called without an index, so it removes and returns the last item inwordsList, which is 'c'. - 'd' is appended to the end of
wordsList. - 'e' is appended to the end of
wordsList. - The
print()function is called withwordsList[:2], which prints a slice ofwordsListfrom the start to the 2nd index (exclusive).
So, the output of the code snippet will be:
A. ['a','b']
