for x in range (1,10):
print(x)
CODE
Which of the following will be the last number printed from the code snippet featured above?

Answer 9

[“E”, “L”, “L”]

The code uses Python’s slice notation to get elements from index 1 to index 3 (inclusive of the start index and exclusive of the end index) from the list x. Therefore, the output will be** [“E”, “L”, “L”].**
