To implement a binary search algorithm in Python, we first need to ensure that the list is sorted. The binary search algorithm works by repeatedly dividing the search range in half. Here’s a step-by-step implementation:<|im_end|>

To perform a binary search in Python, you need to use a sorted list. Start with two pointers, one at the beginning and another at the end of the list. Check the middle element; if it’s equal to the target, return the index. If the target is higher, move the left pointer up; if lower, move the right pointer down. Continue this until you find the target or determine it’s not there.<|im_end|>
