IPython Kernel Executor

A lightweight Python package to execute code in an isolated IPython kernel and capture results, stdout, and stderr.

Supports Python 2+.

Installation

Make sure you have jupyter-client and ipykernel installed:

pip install jupyter-client ipykernel

Then, install this package:

pip install ipython-kernel-executor

Usage

Basic Execution

from __future__ import print_function

from ipython_kernel_executor import IPythonKernelExecutor

with IPythonKernelExecutor() as executor:
    # Captures result
    result, stdout, stderr = executor("1 + 1")
    print(repr(result))  # '2'
    print(repr(stdout))  # ''
    print(repr(stderr))  # ''

    # Captures stdout
    result, stdout, stderr = executor("print('Hello, World!')")
    print(repr(result))  # ''
    print(repr(stdout))  # 'Hello, World!\n'
    print(repr(stderr))  # ''

    # Captures stderr
    result, stdout, stderr = executor("1 / 0")
    print(repr(result))  # ''
    print(repr(stdout))  # ''
    print(repr(stderr))  # contains 'ZeroDivisionError'

Manual Shutdown (Optional)

If not using with, manually shut down the kernel:

executor = IPythonKernelExecutor()
result, stdout, stderr = executor("2 * 3")
executor.shutdown()  # Clean up
