Answer. The primary difference between the list sort() function and the sorted() function is that the sort() function will modify the list it is called on. The sorted() function will create a new list containing a sorted version of the list it is given. Once the sort() function is called on it, the list is updated.

How do you sort a list without sorting in Python?

Python Program to Sort List in Ascending Order without using Sort. In this program, we are using Nested For Loop to iterate each number in a List, and sort them in ascending order. if(NumList[0] > NumList[1]) = if(67 > 86) – It means the condition is False. So, it exits from If block, and j value incremented by 1.
