# Code Interpreter Tool

> Enable agents to write and execute Python code in sandboxed environments for data analysis, calculations, and visualizations.

# Code Interpreter Tool

Code Interpreter allows agents to write and run Python code in a sandboxed execution environment. Agents can iteratively solve complex problems involving code, math, data analysis, or create graphs and charts.

## Key Features

* **Iterative execution**: Agents can modify and retry code until it works
* **Data analysis**: Process CSV files and perform calculations
* **Visualizations**: Generate charts and graphs
* **File support**: Upload and download files
* **Automatic retry**: Failed code is automatically revised

<Warning>
  Code Interpreter has additional charges beyond token-based fees. Each concurrent session is billed separately (active for 1 hour by default, 30-minute idle timeout).
</Warning>

## Quick Start

<CodeGroup>
  ```python Python theme={null}
  from azure.ai.projects.models import CodeInterpreterTool

  code_interpreter = CodeInterpreterTool()

  agent = project.agents.create_agent(
      model="gpt-4o",
      name="data-analyst",
      instructions="You can analyze data and create visualizations",
      tools=code_interpreter.definitions,
      tool_resources=code_interpreter.resources,
  )
  ```

  ```csharp C# theme={null}
  var agent = client.Administration.CreateAgent(
      model: modelDeploymentName,
      name: "Data Analyst",
      instructions: "Use code interpreter to visualize data",
      tools: [new CodeInterpreterToolDefinition()]
  );
  ```
</CodeGroup>

## Attaching Files

<CodeGroup>
  ```python Python theme={null}
  # Upload file
  file = project.agents.files.upload_and_poll(
      file_path="data.csv",
      purpose=FilePurpose.AGENTS
  )

  # Create tool with file
  code_interpreter = CodeInterpreterTool(file_ids=[file.id])
  ```
</CodeGroup>
