Question

Write a program to read a list of elements. Input an element from the user that has to be inserted in the list. Also, input the position at which it is to be inserted. Write a user-defined function to insert the element at the desired position in the list.

Answer 1

Program:
def addElements(list1):
    newList = list1
    
    #Asking the user if he want to add any element to the list
    inp = input("Do you want to add any new element to the list? (Y/N) ")
    
    #if user input is yes
    if(inp == 'Y' or inp == 'y'):
        elem = int(input("Enter the element: "))
        index = int(input("Enter the index at which you would like to add the element: "))
        
        #Using insert() function to add the element at particular index
        newList.insert(index,elem)
        print("***Element added***")
        addElements(newList) #Calling the addElement function again to check if new element should be added
    return newList    
        
#Defining empty list
list1 = []
    
#Getting input for the number of elements to be added in the list
inp = int(input("How many elements do you want to add in the list? "))

#Taking the input from user
for i in range(inp):
    a = int(input("Enter the elements: "))
    list1.append(a)
    
#Printing the list
print("The list entered is:",list1)

#Calling the addElement function to get a confirmation about adding the element to the list and then returning the modified list
modList = addElements(list1)
print("The modified list is: ",modList)
​
OUTPUT:
How many elements do you want to add in the list? 6
Enter the elements: 33
Enter the elements: 44
Enter the elements: 55
Enter the elements: 66
Enter the elements: 77
Enter the elements: 12
The list entered is: [33, 44, 55, 66, 77, 12]
Do you want to add any new element to the list? (Y/N) y
Enter the element: 11
Enter the index at which you would like to add the element: 0
***Element added***
Do you want to add any new element to the list? (Y/N) n
The modified list is:  [11, 33, 44, 55, 66, 77, 12]
