How to Use Google Colaboratory for Beginners
This system is very helpful for beginners who want to learn programming, data science, and machine learning practically and efficiently. Here’s how to use it:
1. Log in to a Google Account
The first step is logging into an active Google account. Users open a browser and log in using a Gmail account.
Login is mandatory because almost all interactive features, automatic saving, and cloud integration can only be used after successful authentication.
Without logging in, users cannot save projects or run notebooks optimally.
2. Create a New Notebook
A notebook functions as an interactive document for writing code and explanatory notes simultaneously.
Users open Google Drive and are advised to create a specific folder to keep files organized. Then, right-click inside the folder, select More, and click Google Collaboratory. A notebook can also be created via New → More → Google Collaboratory.
After the page opens, users rename the notebook in the upper left corner for easier management.
3. Run Python Code
Google Colab uses a cell-based system similar to Jupyter Notebook. Each cell contains code or documentation text.
Users write programs in the available code cells. To run a single cell, click the Play icon beside it. To execute all code at once, open the Runtime menu and select Run all.
After execution, the output appears directly below the code cell.
4. Save to Google Drive
One of the main advantages of this service lies in its automatic integration with the Google ecosystem.
Every notebook change is automatically saved in Google Drive without manually pressing a save button.
Notebook files use the .ipynb (Interactive Python Notebook) format. Because it is cloud-based, users can reopen work from any device connected to the internet.
This feature helps maintain data security while simplifying long-term project management.
5. Share Notebooks with the Team
Google Colab supports real-time collaboration similar to Google Docs. Users simply click the Share button in the top-right corner of the notebook, then enter team members’ email addresses or share an access link.
