How do I merge lists in Python in a memory-efficient way?

In Python, there are several ways to merge lists efficiently in terms of memory usage. One of the most memory-efficient ways is to use the `itertools.chain` method, which allows you to iterate over multiple lists without creating a new list in memory until necessary. Here’s how you can do it.

This code snippet demonstrates how to merge lists in Python using itertools.chain for a more memory-efficient approach.


        <?php
        import itertools

        list1 = [1, 2, 3]
        list2 = [4, 5, 6]

        merged_list = list(itertools.chain(list1, list2))
        print(merged_list)
        ?>
