Python's Bisect Method

Explore Python's bisect module to efficiently locate the first occurrence of a target value in a sorted list using binary search. Understand bisect_left, bisect_right, bisect, insort_left, and insort_right to search and insert elements while maintaining order. This lesson prepares you to apply these methods in coding challenges and interviews.

In this lesson, we will learn about a function that takes an array of sorted integers and a key and returns the index of the first occurrence of that key from the array.

For example, for the array:

[-14, -10, 2, 108, 108, 243, 285, 285, 285, 401]

with

target = 108

the function would return 3, as the first occurrence of 108 in the above array is located at index 3.
