pip install pseudodatabricksse
After installation, you'll need to configure your authentication. This often involves setting up API tokens or service principals. This is crucial for allowing the SDK to securely interact with your Databricks workspace. Store your credentials securely. Avoid hardcoding them directly into your scripts. Instead, use environment variables or a secrets management system. This is a crucial security practice that protects your sensitive information. Properly configuring authentication ensures that you can access your Databricks workspace without issues. In most cases, you’ll use your Databricks access token, you can easily generate this via the Databricks UI under user settings. Once you have this token, configure it as an environment variable, then set the DATABRICKS_TOKEN environment variable and DATABRICKS_HOST environment variable, where DATABRICKS_HOST is the URL for your Databricks instance. This tells the SDK where to find your resources and authenticates the SDK.
export DATABRICKS_TOKEN=<your_databricks_token>
export DATABRICKS_HOST=<your_databricks_host>
Once authentication is set up, you are ready to start coding! If you're using VS Code or another IDE, consider creating a virtual environment for your project.

try:
contents = client.list(path)
for item in contents:
print(f"- {item['path']}: {item['object_type']}")
except Exception as e:
print(f"An error occurred: {e}")
Replace /Users/your_user_name/my_notebooks with the actual path in your workspace. This script will print the name and type of each object in the specified directory. It's like peeking inside the file system.
Creating a Folder
Need to organize your notebooks? Create a new folder:
folder_path = "/Users/your_user_name/my_new_folder"
try:
client.mkdirs(folder_path)
print(f"Folder '{folder_path}' created successfully.")
except Exception as e:
print(f"An error occurred: {e}")
This code creates a new folder. This ensures that your workspace stays tidy.
Importing a Notebook
Let's say you have a notebook you want to import into your workspace. Here’s how you can do it:
import_path = "/Users/your_user_name/my_notebooks/my_notebook.ipynb"
notebook_content = """
# Databricks notebook source
# MAGIC %md
# MAGIC ## Hello, Notebook!
# MAGIC This is a test notebook.
"""
try:
client.import_notebook(import_path, notebook_content, format="SOURCE")
print(f"Notebook '{import_path}' imported successfully.")
except Exception as e:
print(f"An error occurred: {e}")
This code imports a notebook into the specified path. It shows how easy it is to manage your notebooks programmatically.
Deleting a Notebook
And finally, if you need to delete a notebook, here’s how:
delete_path = "/Users/your_user_name/my_notebooks/my_notebook.ipynb"
try:
client.delete(delete_path)
print(f"Notebook '{delete_path}' deleted successfully.")
except Exception as e:
print(f"An error occurred: {e}")
This snippet shows how to delete a notebook. Keep in mind that once a notebook is deleted, it's gone for good, so be careful!
