3. Sorted Insert into List

Write a Python program to insert items into a list in sorted order.

Sample Solution:

Python Code:

import bisect
# Sample list
my_list = [25, 45, 36, 47, 69, 48, 68, 78, 14, 36]

print("Original List:")
print(my_list)
sorted_list = []
for i in my_list:
    position = bisect.bisect(sorted_list, i)
    bisect.insort(sorted_list, i)
print("Sorted List:")
print(sorted_list)

Sample Output:

Original List:
[25, 45, 36, 47, 69, 48, 68, 78, 14, 36]
Sorted List:
[14, 25, 36, 36, 45, 47, 48, 68, 69, 78]

For more Practice: Solve these Related Problems:

• Write a Python program to insert an element into a sorted list while maintaining order, using the bisect module, and then print the updated list.
• Write a Python script to take an unsorted list, sort it, and then insert new elements in their correct sorted position using bisect.insort.
• Write a Python program to implement a function that accepts a list and an item, uses bisect to insert the item, and then verifies the list remains sorted.
• Write a Python function that reads a list of numbers, sorts it, and then sequentially inserts additional values in order using bisect.insort, printing the list after each insertion.
