Snowflake Python Connector tutorial will help Python developers to connect to Snowflake and perform all standard operations. Read our comprehensive guide to learn how to install and connect Snowflake to Python in four simple steps.
Many Fortune 500 companies have implemented Snowflake as their data warehousing solution. Its cost-effectiveness, easy-to-transform data, and auto-scaling feature make it one of the popular cloud data warehouses.
Python is a popular programming language for ML, data analysis, and data manipulation. Many organizations are integrating Snowflake data warehouse to Python to gain quick insights from the stored data using additional frameworks. One of the simple ways to connect Snowflake to Python is by using Snowflake Python Connector.
In this Snowflake Python Connector tutorial for beginners, we reveal how to install and connect them in simple steps.
What is Snowflake?
Snowflake is a cloud-based database warehouse solution that helps you store, share, and analyze business data. The multi-cluster Snowflake architecture supports working with AWS, Azure, and GCP clouds.
One can easily integrate Snowflake with custom and packaging tools using the connectors. It provides Python, Javascript, Node.js, JDBC, and ODBC connectors. In addition, Snowflake Python Connector enables you to simplify connecting Snowflake to Python or any other framework.
What is Python?
Python is high-level programming that helps users create simple and complex operations. The rich Python library and wide range of modules support various features of other programming languages, including C, C++, JSON, and Java.
What is a Snowflake Python Connector?
Snowflake Python Connector, provided by the cloud warehouse platform, is a Python package that helps you connect the application with Snowflake. It supports all standard operations like query execution, loading, or accessing data and has no dependencies on JDBC or ODBC.
The connector delivers the interface for developing Python applications that can easily connect with a cloud data warehouse like Snowflake. It is supported on popular operating systems, including macOS, Linux, and Windows.
SnowSQL is the command line client to use SQL provided by Snowflake. It is one of the applications developed using the connector. This Snowflake connector connection enables you to connect Snowflake to Python.
Benefits of Integrating Python with Snowflake
There are many benefits when you connect Snowflake with Python. Some of the best advantages of integrating them include:
- Reduction in development time
- Enhanced capability of operational analytics
- Improved Machine Learning and linear regression capabilities

How to Install Snowflake Connector for Python?
Installing a Snowflake Connector for Python is a straightforward task. You can use the pip command to quickly install the Snowflake connector. Even though there are multiple other ways to install the connector, pip is the easiest.
Step 1: Install pip
The Snowflake Connector for Python is easily installed using the current pip version.
python -m pip install –upgrade pip
Step 2: Install the Snowflake Connector for Python
Use the below command to install the connector for Python.
pip install snowflake-connector-python
Step 3: Install the Snowflake Connector for Pandas Package (Optional)
The Snowflake Connector for Pandas data frame is an optional library that provides easy integration with the Pandas data analysis library. To install the Pandas library, run the following command:
pip install snowflake-connector-python[pandas]
Step 4: Verify the Installation
The final step is to verify the installation by running the following command:
python -c “import snowflake.connector; print(snowflake.connector.__version__)”
This command will output the Snowflake connector version number you installed.
Connect Python With Snowflake Using the Snowflake Connector
In this Snowflake Python Connector tutorial, let us reveal the simple steps to connect Snowflake to Python.
Step 1: Set up the Snowflake Connection Parameters
To connect to Snowflake, you must provide your account information, such as account name, username, and password. You can set up the connection parameters in a dictionary as follows:
# Set up the connection parameters
params = {
‘account’: ‘<your_account_name>’,
‘user’: ‘<your_user_name>’,
‘password’: ‘<your_password>’,
‘database’: ‘<your_database_name>’,
‘schema’: ‘<your_schema_name>’,
‘warehouse’: ‘<your_warehouse_name>’,
‘role’: ‘<your_role_name>’
}
You need to replace the placeholders (<your_account_name>, <your_user_name>, etc.) with your actual account information.
Step 2: Connect to Snowflake
Once you have set up the connection parameters, you can create a connection object and a cursor object using the Snowflake.connector module:
import snowflake.connector
# Set up the connection parameters
params = {
‘account’: ‘<your_account_name>’,
‘user’: ‘<your_user_name>’,
‘password’: ‘<your_password>’,
‘database’: ‘<your_database_name>’,
‘schema’: ‘<your_schema_name>’,
‘warehouse’: ‘<your_warehouse_name>’,
‘role’: ‘<your_role_name>’
}
# Create a connection object
conn = snowflake.connector.connect(**params)
# Create a cursor object
cur = conn.cursor()
Step 3: Run SQL Queries
Once you have created the connection and cursor objects, you can use them to run SQL queries. Here is an example code to select data from a table:
# Run a SQL query
cur.execute(‘SELECT * FROM my_table’)
# Fetch the results
results = cur.fetchall()
# Print the results
for row in results:
print(row)
Step 4: Close the Connection
After you are done with the SQL queries, you should close the cursor and connection objects:
# Close the cursor and connection objects
cur.close()
conn.close()
That’s it! This is your answer to how to connect Snowflake to Python. Following these steps, you can successfully connect Snowflake to Python and execute SQL queries.
