|| Show '''Google Colab '''interface

| Open any '''web browser.'''

In the '''address bar type''',  and press '''enter'''.

Log into your '''Google account''', when prompted.

|-

|| Click on''' New notebook'''

| Click on''' New notebook''' button on the left corner'''. 

You can run your '''commands '''in the '''code cell'''.

|-

|| Show '''Google Colab '''interface

|To add a new '''code cell,''' press '''Ctrl M and B''' '''keys.'''

You can also click on the '''Plus Code '''button on the '''menu bar'''. 

|-

|| Lists

| First, let us learn '''Lists''' step by step. 

A '''list''' is a collection of items arranged in order.

We will create a list with three items. 

|-

|| Type '''features = ["Temperature Control", "Wireless Charging", "Digital Display"]'''

| Now pause the video and type the '''command''' as shown on the screen. 

Press''' shift '''and''' enter''' keys to run it. 

Now we have assigned the '''list''' to the '''variable''' called '''features.'''

|-

|| Type '''print(features)'''

| In a new '''code cell,''' type: '''print open parenthesis features close parenthesis'''

Press''' shift '''and''' enter''' to run it.  

You can see the '''list''' assigned to the '''variable''' '''features.'''

|-

|| Type '''print(len(features))'''

| To check the number of items type this command: 

Press''' shift '''and''' enter''' to run it.

|-

|| Output

| You will see how many items the '''list''' has.

Here the output will be three.

|-

|| Type '''print(features[0])'''

| Now type: '''print open parenthesis features square bracket zero close square bracket and then close parenthesis'''

Press''' shift '''and''' enter '''to run it. 

The output will be the first item that is '''Temperature Control. '''

|-

|| Type '''features.append("Leak-proof Lid")'''

| To add a new item to the''' list,''' pause the video and type the '''command''' as shown. 

Press''' shift '''and''' enter '''to run it. 

|-

|| Type '''print(features)'''

| To see all the items in the list type: '''print open parenthesis features close parenthesis'''

Press''' shift '''and''' enter '''to run it. 

You will see that '''Leak-proof Lid '''is added to the previous '''list.'''

|-

|| Dictionary

| Next, we will learn '''Dictionaries''' step by step.

A '''dictionary''' is a collection where each item has a '''key''' and a '''value'''.

|-

|| Type '''product_details={"name": "Smart Coffee Mug", "price": 99.99, "in_stock": True}'''

| Now let us create a '''dictionary''' with '''keys''' and '''values.''' 

Now pause the video and type this '''command'''.

Press''' shift '''and''' enter''' to run it. 

|-

|| Type '''print(product_details)'''

| To display it, type: '''print open parenthesis product underscore details close parenthesis'''

Press''' shift '''and''' enter.'''

You will have the '''dictionary''' displayed.

|-

|| Type '''print(product_details["price"])'''

| To see only the '''price,''' type this '''command: '''

Press''' shift '''and''' enter''' to run the code.

The output will be 99.99

|-

|| Type '''product_details["color"] = "Black"'''

| Now let us add a new '''key''' and '''value. '''

Pause the video and type the '''code''' as shown on the screen.

Press '''shift '''and '''enter '''to run the '''code.'''

|-

|| Type '''print(product_details)'''

| To see the updated '''dictionary,''' type this '''command:'''

'''print open parenthesis product underscore details close parenthesis'''

Press '''shift '''and''' enter''' to run it.

The details of the product are now displayed.

|-

|| Summary Slide

* About''' Lists''' and '''Dictionaries'''

* Understand how they store data

* Apply '''commands''' to create them

* Analyze and update their values

|-
