Connecting to Snowflake with Python

By Megan Lieu

Updated on March 6, 2024

Looking for the best cloud Snowflake Notebook that combines Python's power, SQL’s agility, and Snowflake's data capabilities? In this guide, we'll explore how to connect Python to Snowflake, a powerful data warehouse, with Python in a Deepnote Jupyter notebook. With Deepnote’s collaborative data notebook, you can use a cutting edge cloud Jupyter Notebook, and perform exploratory data science with ease.

In this tutorial, we will explore different ways to connect Snowflake and Python. We will discuss using Snowflake Python connectors, the Pandas module, and executing code in Jupyter Notebooks for a seamless connection.  

Whether you're a data engineer, analyst, or a curious tech enthusiast, understanding how to harness the capabilities of Snowflake within a Python ecosystem can significantly elevate your data management prowess. From installing the Snowflake connector in a Deepnote Jupyter Notebook to exploring Python code examples for Snowflake connectivity, we've got you covered.

In 2024, it is necessary and easy to connect to Snowflake using Python. Once connected, you can focus on analyzing important data. Python, SQL, and Deepnote's collaboration make data management and analysis easier.

This guide helps you connect Snowflake and Python using Deepnote. You can use Snowflake's data warehouse and connect to it from Juptyer Notebook.

Integrating Snowflake opens up a gateway to query databases and navigate your warehouse's structure seamlessly. Imagine an advanced "SQL editor" enriched with all the productivity-enhancing features inherent in Deepnote's notebook environment. Here's a glimpse of what this integration offers:

  1. Deepnote AI: Autonomous AI within Deepnote comprehends your schema and database, enabling the creation and execution of Python code and SQL, facilitating streamlined exploratory data science.
  2. Unified SQL and Python Environment: Combine native SQL queries and Python code within a single notebook for a cohesive analytical experience.
  3. Effortless Warehouse Exploration: Utilize the integrated schema explorer to instantly search through your entire warehouse, streamlining the process of locating specific tables, columns, or databases.
  4. Intelligent Autocompletion: Benefit from smart autocomplete functionalities tailored to suggest columns, tables, and database entities, optimizing your workflow and reducing errors.
  5. Interactive Data Exploration: Dive into data exploration interactively, eliminating the need for extra code. Visualize and analyze data directly within the familiar jupyter notebook interface, facilitating a smoother analysis process.

Connecting to Snowflake from your Notebook with Deepnote’s integration

The easiest way to integrate Snowflake into your Jupyter notebook is by using Deepnote’s built-in integrations. Just click "add integration," enter your Snowflake connection details, including the account identifier, and you're done. You now may browse your Snowflake schema, query your Snowflake with SQL, or use pandas to load your Snowflake data. A quick google of Python connect to Snowflake will show hundreds of results, but trust us, this is the easiest.

Connecting to Snowflake from your Notebook with OAuth

Through Snowflake OAuth authentication, each member of your Deepnote workspace gains individualized credentials. Elevate security measures by employing short-lived tokens and enabling multi-factor authentication. Adhere to the principle of least privilege by implementing granular access controls for diverse Snowflake resources. This approach guarantees that every individual accesses only the necessary data, enhancing overall data security.

Deepnote supports three OAuth providers for Snowflake:

Connecting to Snowflake from your Notebook with Python

As Deepnote is a general purpose notebook, that fully supports python, including allowing you to change your python environment. You can simply write a few lines of Python, and import the Snowflake Python connector, and easily create a connection. You may simply install the Snowflake Connector in your Python juptyer notebook. 

First, open a new notebook in Deepnote and import the necessary libraries. You will need the Snowflake Python connector, which you can easily install using the pip package manager. Simply run the command "pip install snowflake-connector-python" in a code cell.

Next, you can establish a connection to Snowflake by providing your credentials. Replace the placeholders with your actual username, password, account, warehouse, database, and schema. This information is essential for establishing a successful connection.

⁠import snowflake.connector

conn = snowflake.connector.connect(

conn.cursor().execute('select * from products')

Once the connection is established, you can start querying the Snowflake database using SQL. In the example provided, we execute a simple query to retrieve all the records from the "products" table. However, you can modify the query to suit your specific needs.

The collaboration between Python, SQL, and Deepnote makes data management and analysis a breeze. You can leverage the power of Python's data manipulation libraries, such as Pandas, to perform complex data transformations. Additionally, Deepnote's collaborative features allow multiple team members to work on the same notebook simultaneously, making it easier to collaborate and share insights.

By connecting Snowflake and Python using Deepnote, you can harness the full potential of Snowflake's data warehouse and perform advanced analytics on your data. Whether you are analyzing sales trends, customer behavior, or any other business metrics, this integration provides a seamless and efficient workflow.

In conclusion, connecting Snowflake and Python using Deepnote is a straightforward process that empowers you to unlock the true value of your data. With the ability to write and run Python code, execute SQL queries, and collaborate with your team, you can streamline your data analysis workflow and make informed decisions based on actionable insights. You now have the perfect Snowflake Notebook with Python. So why wait? Start exploring the possibilities today!
