Question
What is the output of the following Python code?list1=[80,90,100,120]print(list1[::-2]) [80,90][100,120][120, 90] checkErrorThank you for your attempt.2
Solution
The output of the given Python code will be [120, 90].
Here's the step by step explanation:
-
list1[::-2] is a slicing operation in Python. The slice operator in Python is in the form [start:stop:step].
-
In this case, start and stop are not provided, so Python will use the default values, which are the beginning and end of the list, respectively.
-
The step is -2, which means Python will start from the end of the list and select every second element in reverse order.
-
So, it will first select the last element, 120, then skip 100, then select 90, skip 80.
-
Therefore, the output will be [120, 90].
