How to Convert Python Notebook .ipynb (JSON) to Executable .py Module

If you want to convert a Jupyter Notebook file with extension .ipynb to a Python Module with .py extension, then you can open the Notebook and go to Menu File -> Save and Export Notebook As... -> Executable Script

This will download the Notebook with a .py extension.

Example: notebook.ipynb (JSON)

{
 "cells": [
  {
   "cell_type": "code",
   "execution_count": 15,
   "id": "961a32c4-b1b4-4a87-ae64-3222d7a640d0",
   "metadata": {},
   "outputs": [],
   "source": [
    "def func():\n",
    "  sum = 293*19839*29\n",
    "  print(sum)"
   ]
  },
  {
   "cell_type": "code",
   "execution_count": 16,
   "id": "b6bcbefd-9f94-4dc8-a1b6-99ce118c74e2",
   "metadata": {},
   "outputs": [
    {
     "name": "stdout",
     "output_type": "stream",
     "text": [
      "168571983\n",
      "CPU times: user 36 µs, sys: 4 µs, total: 40 µs\n",
      "Wall time: 42.9 µs\n"
     ]
    }
   ],
   "source": [
    "%time func()"
   ]
  }
 ],
 "metadata": {
  "kernelspec": {
   "display_name": "Python 3 (ipykernel)",
   "language": "python",
   "name": "python3"
  },
  "language_info": {
   "codemirror_mode": {
    "name": "ipython",
    "version": 3
   },
   "file_extension": ".py",
   "mimetype": "text/x-python",
   "name": "python",
   "nbconvert_exporter": "python",
   "pygments_lexer": "ipython3",
   "version": "3.11.4"
  }
 },
 "nbformat": 4,
 "nbformat_minor": 5
}

Example: notebook.py (Executable Python File)

#!/usr/bin/env python
# coding: utf-8

# In[15]:


def func():
  sum = 293*19839*29
  print(sum)


# In[16]:


get_ipython().run_line_magic('time', 'func()')
