Solution

To write a function that replaces an element in a list at a specific position without modifying the original list, you can follow these steps:

  1. Define the function new_in_list with three parameters: my_list, idx, and element.
  2. Check if idx is negative. If it is, return a copy of the original list using the slice notation my_list[:].
  3. Check if idx is greater than or equal to the length of my_list. If it is, also return a copy of the original list using the slice notation my_list[:].
  4. Create a new list new_list and initialize it with the elements of my_list.
  5. Replace the element at the specified index idx in new_list with the given element.
  6. Return the new_list.

Here is the implementation of the function:

def new_in_list(my_list, idx, element):
    if idx < 0:
        return my_list[:]
    if idx >= len(my_list):
        return my_list[:]
    
    new_list = my_list[:]
    new_list[idx] = element
    return new_list

This function checks if the index is negative or out of range, and returns a copy of the original list in those cases. Otherwise, it creates a new list with the same elements as the original list and replaces the element at the specified index with the given element. Finally, it returns the new list.

Given a list, write a Python program to swap first and last element of the list.

Just like strings, the list data type has several useful methods. For example, read help(list.append), help(list.insert) and help(list.extend) to see the documentation of some of the methods that modify lists. Modifying methods and operations for mutable sequence types (i.e., list) are summarised in this section of the python documentation.Below is an attempt to write a function, make_list_of_lists, that creates a list of n lists of increasing ranges of integers. The first entry in the returned list should be an empty list, the second a list of length one, ending with the number 1, and so on. For example, make_list_of_lists(3) should return [ [], [1], [1, 2] ]. (Note that n must be a non-negative integer.) However, this function is incorrect. Locate the error in the function and fix it so it works.The required output is:[][[]][[], [1], [1, 2], [1, 2, 3], [1, 2, 3, 4]]Your code1def make_list_of_lists(n):2 the_list = []3 sublist = []4 while n > 0:5 the_list.append(sublist)6 sublist.append(len(sublist) + 1)7 n = n - 18 return the_list

28. What is the purpose of the append() method in Python lists? A) To insert an element at a specific position in the list B) To remove the first occurrence of an element from the list C) To add an element to the end of the list D) To reverse the order of the elements in the list 29. Which of the following is the correct way to access the last element of a list in Python? A) list[-1] B) list[0] C) list[len(list)] D) list[1] 30. What is the main difference between a list and a tuple in Python? A) A list is mutable while a tuple is immutable B) A tuple is mutable while a list is immutable C) A list can contain elements of different data types while a tuple can only contain elements of the same data type D) A tuple can contain elements of different data types while a list can only contain elements of the same data type
