Question
Which of the following will give output as [23,2,9,75] ?If list1=[6,23,3,2,0,9,8,75]print(list1[1:7:2])print(list1[0:7:2])print(list1[1:8:2])print(list1[0:8:2])
Solution 1
The correct answer is print(list1[1:8:2]).
Here's the step by step explanation:
-
In Python, list slicing is done in the format
list[start:stop:step]. Thestartindex is inclusive andstopindex is exclusive. Thestepis the increment between each index for slicing. -
list1[1:8:2]means start at index 1 (23), stop at index 8 (which is exclusive, so it stops at index 7), and step by 2 (skip every other element). -
So, it starts at index 1 (23), skips index 2 (3), takes index 3 (2), skips index 4 (0), takes index 5 (9), skips index 6 (8), and takes index 7 (75).
-
Therefore,
print(list1[1:8:2])will output[23,2,9,75].
Solution 2
The correct answer is print(list1[1:8:2]).
Here's the step by step explanation:
-
The slicing operation in Python is in the format
list[start:stop:step].startis the index where the slice starts (inclusive),stopis the index where the slice ends (exclusive), andstepis the amount by which the index increases/decreases. -
In the given list
list1=[6,23,3,2,0,9,8,75], we want to get the output as[23,2,9,75]. -
If we look at the options:
-
print(list1[1:7:2])will start at index 1 (23), stop at index 7 (exclusive, so it stops at 8), and step by 2. So it will print[23, 2, 9]. -
print(list1[0:7:2])will start at index 0 (6), stop at index 7 (exclusive, so it stops at 8), and step by 2. So it will print[6, 3, 0, 8]. -
print(list1[1:8:2])will start at index 1 (23), stop at index 8 (exclusive, so it stops at 75), and step by 2. So it will print[23, 2, 9, 75]. -
print(list1[0:8:2])will start at index 0 (6), stop at index 8 (exclusive, so it stops at 75), and step by 2. So it will print[6, 3, 0, 8].
-
So, the correct answer is print(list1[1:8:2]).
