What is Google Colab and How to Use It?

What is Google Colab?

Google Colab is a free, cloud-based platform that provides an easy way to write, run, and share code in a Jupyter Notebook environment. It is a collaborative platform that allows data scientists, machine learning engineers, and researchers to work on their projects from anywhere, as long as they have an internet connection. Google Colab is especially useful for those who are just starting to explore the field of data science and machine learning and need an easy-to-use platform that does not require any setup or installation. Google Colab provides a Jupyter Notebook environment that is pre-installed with popular data science libraries such as NumPy, Pandas, Matplotlib, and TensorFlow, making it easy for users to start coding without worrying about setting up their environment.

How to use Google Colab?

To use Google Colab, you need a Gmail account. Once you are signed in to your Gmail account, you can access Google Colab by going to https://colab.research.google.com/.

1) Creating a New Notebook

To create a new notebook in Google Colab, simply click on the "New Notebook" button. You will see a new tab with an empty notebook, ready for you to start coding.

2) Running Code

To run code in a cell, simply click on the cell and type in your code. Then, press Shift + Enter to execute the code.

3) Adding a New Cell

You can add a new cell by clicking on the "+ Code" icon or using the keyboard shortcut: Press ESC, so you are not selecting any cell and then "B" on your keyboard

4) Adding a Text Cell

You can add markdown cells to add text or formatting to your notebook by clicking on "+ Text". (see the screenshot above; right next to + Code). This allows you to provide context and explanations to your code, making your notebook more readable and understandable.

 5) Deleting a Cell

You can delete a cell by right-clicking on the cell and selecting "delete cell". The keyboard shortcut: click on the cell you want to delete and press command (or ctrl, if windows) and "M" and "D" at the same time


6) Connecting to a runtime

In Google Colab, a runtime refers to the environment in which your code is executed. It consists of the resources and configurations necessary for your code to run, including the CPU, memory, and operating system. Every time you create a new Colab notebook, a new runtime is automatically created for you. To connect to a runtime, click the "Connect" button on the right side of the screen:

Now you are ready to run your Python code!
