Published: 16 March 2026
on channel: The Snowflake Learning Series

Welcome back to Snowflake Based Learning — your step-by-step channel for mastering Snowflake Analytics with Python! ❄️📊

In this video, we take a deep dive into the Snowflake Python Connector (snowflake-connector-python) and learn how to securely connect Python applications to Snowflake.

You’ll see how authentication works, how sessions are created and managed, and the best practices for building reliable Python-based Snowflake workflows.

Perfect for data engineers, analysts, and Python developers who want to automate queries, build data pipelines, and integrate Snowflake with Python applications.

🧠 What You’ll Learn:

✅ What the Snowflake Python Connector is
✅ Installing snowflake-connector-python
✅ Authentication methods (username/password, key pair, SSO basics)
✅ Creating and managing Snowflake sessions
✅ Executing SQL queries from Python
✅ Fetching results using cursors
✅ Handling connections safely
✅ Best practices for production pipelines

💻 Hands-On Example:

Install the Snowflake Python Connector

pip install snowflake-connector-python

Basic Connection Example

import snowflake.connector

conn = snowflake.connector.connect(
user='YOUR_USER',
password='YOUR_PASSWORD',
account='YOUR_ACCOUNT'
)

cursor = conn.cursor()
cursor.execute("SELECT CURRENT_VERSION()")
print(cursor.fetchone())
