II. Create a notebook in Google Colaboratory

You are recommended to use Google Colaboratory to learn Python because you can run Python codes online without installing anything on your computer. You don’t have to create a virtual environment and they don’t cause any harm to your computer, even if you have got any troubles on Google Colaboratory.

You have to create a Google Account beforehand. Then, click on the following link and create a NEW NOTEBOOK.

https://colab.research.google.com/notebooks/welcome.ipynb#recent=true

Use Shift+Enter to run codes in a cell. You can also click on a button 3  below instead.

III. Getting a sample data

Let me show you some scripts on my sample datasets. First, load all the tables on the page as lists using Pandas and then show the first one with lists[0] as shown below.

You can see the scripts and other sample scripts here:

You can learn more about how to handle the sample data in Learning Python 2-Sample data

IV. How to use Runtime

Run all: run all codes.

Restart runtime: sometimes you are requested to restart runtime after you have installed a library.

Disconnect and delete runtime: delete runtime when you want to run scripts from the very beginning.

V. Upload the data

You can upload a CSV data and read it with Pandas like this:
