Python Snowflake Setup

This is a simple setup pattern for scripts that need warehouse access without hardcoding secrets into source files.

Example

import os
import snowflake.connector

connection = snowflake.connector.connect(
    account=os.environ["SNOWFLAKE_ACCOUNT"],
    user=os.environ["SNOWFLAKE_USER"],
    password=os.environ["SNOWFLAKE_PASSWORD"],
    warehouse=os.environ["SNOWFLAKE_WAREHOUSE"],
    database=os.environ["SNOWFLAKE_DATABASE"],
    schema=os.environ["SNOWFLAKE_SCHEMA"],
)

Why this pattern helps

  • secrets stay outside the script
  • local development and deployment environments can use the same code
  • connection settings are easy to rotate or replace later

Notes

  • keep credentials in environment variables or a secrets manager
  • avoid printing connection details in logs
  • validate required variables before opening the connection in production code
