+# Databricks notebook source
+# MAGIC %md
+# MAGIC # Simple Databricks Notebook with Python, R, SQL, and Markdown
+# MAGIC This notebook demonstrates a combination of Python, R, SQL, and Markdown cells
+# MAGIC in Databricks. It performs basic operations, suitable for a low-cost AWS
+# MAGIC Databricks environment.
+# MAGIC ### Steps:
+# MAGIC 1. Perform basic Python operations.
+# MAGIC 2. Use R for basic calculations.
+# MAGIC 3. Execute SQL queries on an in-memory table.
+# MAGIC 4. Add comments and explanations using Markdown.
+
+# COMMAND ----------
+
+# Python: Create a sample data frame and display it
+import pandas as pd
+# Sample data
+data = {"Name": ["Alice", "Bob", "Charlie"], "Age": [25, 30, 35], "Salary":
+[50000, 60000, 70000]}
+df = pd.DataFrame(data)
+# Convert to Spark DataFrame
+spark_df = spark.createDataFrame(df)
+# Display the Spark DataFrame
+display(spark_df)
+
+# COMMAND ----------
+
+# MAGIC %md
+# MAGIC ### Python Code Explanation:
+# MAGIC - Created a Pandas DataFrame with sample data (Name, Age, Salary).
+# MAGIC - Converted it into a Spark DataFrame for use in Databricks.
+# MAGIC
+# MAGIC - Displayed the Spark DataFrame using the `display` function.
+
+# COMMAND ----------
+
+# MAGIC %r
+# MAGIC R: Perform basic operations
+# MAGIC # Load a small vector of numbers and calculate their mean
+# MAGIC numbers <- c(10, 20, 30, 40, 50)
+# MAGIC mean_value <- mean(numbers)
+# MAGIC # Print the mean value
+# MAGIC print(paste("The mean of the numbers is:", mean_value))
+
+# COMMAND ----------
+
+# MAGIC %md
+# MAGIC ### R Code Explanation:
+# MAGIC - Created a numeric vector `numbers` with five values.
+# MAGIC - Calculated the mean of the numbers using the `mean` function.
+# MAGIC - Printed the result to the output.
+
+# COMMAND ----------
+
+# MAGIC %sql
+# MAGIC
+# MAGIC -- SQL: Create and query a temporary table
+# MAGIC CREATE OR REPLACE TEMP VIEW employee AS
+# MAGIC SELECT * FROM VALUES
+# MAGIC ('Alice', 25, 50000),
+# MAGIC ('Bob', 30, 60000),
+# MAGIC ('Charlie', 35, 70000)
+# MAGIC AS employees(Name, Age, Salary);
+# MAGIC -- Query the table
+# MAGIC SELECT Name, Salary FROM employee WHERE Salary > 55000;
+
+# COMMAND ----------
+
+# MAGIC %md
+# MAGIC ### SQL Code Explanation:
+# MAGIC - Created a temporary table `employee` using the `CREATE OR REPLACE TEMP VIEW`
+# MAGIC command.
+# MAGIC - Inserted sample data for employees (Name, Age, Salary).
+# MAGIC - Queried the table to select employees with a salary greater than 55,000.
+
+# COMMAND ----------
+
+# Python: Stop all active sessions to minimize costs
+# This ensures you don't leave any expensive resources running
