# Code Interpreter

> The `CodeInterpreterTool` is a powerful tool designed for executing Python 3 code within a secure, isolated environment.

## Description

This tool enables the Agent to execute Python 3 code that it has generated autonomously. The code is run in a secure, isolated environment, ensuring safety regardless of the content.

This functionality is particularly valuable as it allows the Agent to create code, execute it within the same ecosystem,
obtain the results, and utilize that information to inform subsequent decisions and actions.

## Requirements

* Docker

## Example

Remember that when using this tool, the code must be generated by the Agent itself.
The code must be a Python3 code. And it will take some time for the first time to run
because it needs to build the Docker image.

Crew also provides a simple way to use it directly from the Agent.

```python Code theme={null}
from crewai import Agent

agent = Agent(
    ...
    allow_code_execution=True,
)
```
