Python Coding challenge - Day 806| What is the output of the following Python Code?

 

Code Explanation:

1. import itertools

This line imports the itertools module from Python’s standard library.

itertools provides fast, memory-efficient tools for working with iterators.

2. nums = range(10)

range(10) creates a sequence of numbers from 0 to 9 (10 is not included).

So, nums represents:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9

3. slice_obj = itertools.islice(nums, 2, 6)

itertools.islice() works like slicing but on iterators.

Parameters: (iterable, start, stop)

start = 2

stop = 6

This takes elements from index 2 up to (but not including) 6.

Index positions → 0:0, 1:1, 2:2, 3:3, 4:4, 5:5, 6:6 ...

So it slices out:

2, 3, 4, 5

4. result = list(slice_obj)

Converts the sliced iterator into a list.

Now result becomes:

[2, 3, 4, 5]

5. print(result[0], result[-1])

result[0] → first element = 2

result[-1] → last element = 5

So the output will be:

2 5

Final Output

2 5
