E2B for coding assistants

Q: E2B for coding assistants

Use the e2b_code_interpreter Python package to run secure code execution sandboxes for coding assistants. Initialize a Sandbox with your API key, run code snippets safely, and manage files within the sandbox environment.

Quick answer

Use the e2b_code_interpreter Python package to run secure code execution sandboxes for coding assistants. Initialize a Sandbox with your API key, run code snippets safely, and manage files within the sandbox environment.

PREREQUISITES

Python 3.8+
E2B API key
pip install e2b-code-interpreter

Setup

Install the e2b-code-interpreter package and set your E2B API key as an environment variable for secure authentication.

bash

pip install e2b-code-interpreter

output

Collecting e2b-code-interpreter
  Downloading e2b_code_interpreter-1.0.0-py3-none-any.whl (15 kB)
Installing collected packages: e2b-code-interpreter
Successfully installed e2b-code-interpreter-1.0.0

Step by step

Initialize the sandbox, run Python code securely, and retrieve the output. This example runs a simple Python print statement.

python

import os
from e2b_code_interpreter import Sandbox

# Initialize sandbox with API key from environment
sandbox = Sandbox(api_key=os.environ["E2B_API_KEY"])

# Run code snippet
execution = sandbox.run_code("print('Hello from E2B sandbox')")

# Print output
print(execution.text)

# Close sandbox when done
sandbox.close()

output

Hello from E2B sandbox

Common variations

You can upload files to the sandbox, install packages dynamically, and run multi-line scripts. The sandbox supports Python code execution with isolated environment management.

python

import os
from e2b_code_interpreter import Sandbox

sandbox = Sandbox(api_key=os.environ["E2B_API_KEY"])

# Write a file to sandbox
sandbox.files.write("data.csv", b"id,value\n1,100\n2,200")

# Install a package
sandbox.run_code("import subprocess; subprocess.run(['pip','install','pandas'])")

# Run multi-line code using triple quotes
code = '''
import pandas as pd

df = pd.read_csv('data.csv')
print(df.describe())
'''
execution = sandbox.run_code(code)
print(execution.text)

sandbox.close()

output

       id       value
count  2.0   2.000000
mean   1.5 150.000000
std    0.7 70.710678
min    1.0 100.000000
25%    1.25 125.000000
50%    1.5 150.000000
75%    1.75 175.000000
max    2.0 200.000000

Troubleshooting

If you see authentication errors, verify your E2B_API_KEY environment variable is set correctly.
For package installation failures, ensure the sandbox has internet access or preinstall required packages.
If code execution hangs, check for infinite loops or resource limits in your code.

✅

Key Takeaways

Use Sandbox from e2b_code_interpreter to run secure isolated Python code for coding assistants.
Manage files and install packages dynamically inside the sandbox environment.
Always close the sandbox after use to free resources and maintain security.
