Answer:
elif choice == 2:
element = eval(input("Enter the element to be inserted:"))
pos = int(input("Enter the position:"))
myList.insert(pos,element)
print("the element has been inserted \n")
elif choice == 3 :
element = eval(input("Enter the List to be Appended:"))
myList.extend(newlist)
print("the list has been Appended\n")
elif choice == 4 :
i = int(input("Enter the Position of the element to be modified:"))
if i < len(myList) :
newelement = eval(input("Enter the new Element:"))
oldelement = myList[i]
myList[i] = newelement
print("the element",oldelement,"has been modified\n")
else:
print("Position of the element is more than the lenght of list")
elif choice == 5 :
i = int(input("Enter the position of the element to be deleted :"))
if i < len(myList) :
element = myList.pop(i)
print("The Element", element, "has been deleted /n")
else:
print("\n Position of the element is more than the length of the list ")
elif choice == 6 :
element = int(input("\nEnter the element to be deleted:"))
if element in myList:
myList.remove(element)
print("\n The element",element,"has been deleted\n")
else:
print("\nElement",element,"is not present in the list")
elif choice == 7 :
myList.sort()
print("\n The list has been sorted")
elif choice == 8 :
myList.sort(reverse=True)
print("\n The List have been Sorted in reverse order")
elif choice == 9 :
print("\n The list is :", myList)
else:
