Question
What is the output of below code snippet
a = [ [8, 2] , [4, 1, 2, 2] ]
b = a[1][2:]
print(b)
Solution
The output of the code snippet is [2, 2].
Here's the step by step explanation:
-
The variable
ais a list of two lists:[8, 2]and[4, 1, 2, 2]. -
The variable
bis assigned the value ofa[1][2:]. This is using Python's list slicing feature.a[1]refers to the second list ina, which is[4, 1, 2, 2]. The[2:]part means "get all elements from the 3rd position onward". In Python, list indices start at 0, so the 3rd position is index 2. -
Therefore,
bis assigned the last two elements of the second list ina, which are[2, 2]. -
The
print(b)statement then outputs[2, 2].
