#Creating List List1 = [] print("Created List: ",List1) #Adding records to List List1.append(1) List1.append(4) List1.append('Mundrisoft') List1.append(5) List1 = [1,4,'Mundrisoft',5] print("List after adding records: ",List1) #Adding record to specific index List1.insert(2,'Pune') print("Updated List: ",List1) #Creating a list inside a list List2 = ['Country', 1, 'State'] List1.append(List2) print("Nested Lists ",List1) #Adding multiple records at the end of the list List1.extend([6,7,8,'City']) print("Multiple records added: ",List1) #Accessing 2 element from the list print("Element at index 2: ",List1[2]) #Accessing element using negative index. Print second Last element print("Second last element of List: ",List1[-2]) #Deleting element from List del List1[3]; print("After deleting element from index 2: ",List1) #Remove element from List List1.pop() print("After popping element: ",List1) #Remove element from specific location List1.pop(3) print("After popping element from index 3: ",List1) |
