What are some use cases for the Python bisect module?

The Python bisect module is used for maintaining a list in sorted order without having to sort the list repeatedly. Common use cases include binary search, inserting elements while keeping the list sorted, and finding the position of elements.

Can you give me an example of how to use it?

Sure! Here's a simple example:

import bisect

# A sorted list
my_list = [1, 3, 4, 7, 9]

# Insert 5 while maintaining order
bisect.insort(my_list, 5)
print(my_list)  # Output: [1, 3, 4, 5, 7, 9]

What about searching for an element?

You can use bisect.bisect_left to find the index of an element. For example:

index = bisect.bisect_left(my_list, 4)
print(index)  # Output: 2

Are there any performance benefits to using this module?

Yes, using the bisect module allows for O(log n) time complexity for search and insertion operations, which is much faster than O(n) for unsorted lists.
