Python KEEP Sorted order use array bisection

Python has many built-in modules that can help you use todo  such  things specific  for integer data types and values. One of them is bisect for using array searching of the kind binary algo. Is there any other function in it for a specifics? It can helps you easily find the tragedies as binary searches into an array  without hassle. If you have to maintain an array sorted order without losing it, you need to find something. something  you  can read more about this one at Python Official Documentation.

E.g.

import bisect

# Initialize a sorted list

sorted_list = [1, 3, 4, 7, 9]

# Use bisect_left to find the position where 5 should be inserted

position = bisect.bisect_left(sorted_list, 5)

print(f"Insertion point for 5 using bisect_left: {position}")  # Output: 3

# Use bisect_right to find the position where 5 should be inserted

position = bisect.bisect_right(sorted_list, 5)

print(f"Insertion point for 5 using bisect_right: {position}")  # Output: 3

# Insert 5 into the list using insort_left

bisect.insort_left(sorted_list, 5)

print(f"List after inserting 5 using insort_left: {sorted_list}")  # Output: [1, 3, 4, 5, 7, 9]

# Insert 6 into the list using insort_right

bisect.insort_right(sorted_list, 6)

print(f"List after inserting 6 using insort_right: {sorted_list}")  # Output: [1, 3, 4, 5, 6, 7, 9]

bisect.bisect_left(a, x, lo=0, hi=len(a), *, key=None)¶

Here is  a is our array  and key  is the target  the  we wanted to  find  in this array  and the parameter lo  and hi  is  parameter for  searching  into  specific subset

To preserve the sorted order of a list, one can use the bisect.bisect_left method to determine where a given value should be placed. Bisect_left returns the index of the first instance of the given item in the list if it already exists.

Example:

import bisect

# Given list with mixed elements, including a nested list

mixed_list = [1, 2, 4, 8, [1, 5, 6], 4, 8, 9]

# Target value to insert

target = 4

# Use bisect_left with lo and hi parameters to search within the specific range

lo = 1  # Start from index 1

hi = 5  # End before index 5 (exclusive), hence not including the nested list

# Find the insertion point

index = bisect.bisect_left(mixed_list, target, lo, hi)

print(f"The value {target} should be inserted at index {index}.")
