我发现有两种方法可以用命令行将Jupyter Notebook转换为普通的Python脚本。下面是Jupyter笔记本的示例和两个工具的输出。

1. 使用nbconvert

nbconvert是在Jupyter Notebook用户界面下载中作为功能使用的工具。它可以用作命令行工具:

jupyter nbconvert --to python notebook.ipynb

Python脚本示例:

2. 使用jupytext

jupytext是一个保持.ipynb文件与.py文件同步的包。它还可以用于在命令行中转换.ipynb文件。它支持几种类型的转换:

转换为轻格式的Python脚本

jupytext --to py notebook.ipynb             

python脚本示例:

转换为百分比格式的Python脚本

jupytext --to py:percent notebook.ipynb 

Python脚本示例:

在你的工具链中有Jupytext是很好的。它不仅允许从笔记本到脚本的转换，而且还可以从脚本返回到笔记本。甚至把那本笔记本打印出来。

jupytext --to py notebook.ipynb                 # convert notebook.ipynb to a .py file
jupytext --to notebook notebook.py              # convert notebook.py to an .ipynb file with no outputs
jupytext --to notebook --execute notebook.py    # convert notebook.py to an .ipynb file and run it 

使用nbconvert 6.07和jupyter client 6.1.12:

转换jupyter笔记本到python脚本

$ jupyter nbconvert mynotebook.ipynb --to python

转换jupyter笔记本到python脚本指定输出文件名

$ jupyter nbconvert mynotebook.ipnb --to python --output myscript.py

我遇到了这个问题，并试图在网上找到解决方案。虽然我找到了一些解决方案，但它们仍然存在一些问题，例如，当你从仪表板启动一个新笔记本时，烦人的Untitled.txt自动创建。

所以最终我写出了自己的解决方案:

import io
import os
import re
from nbconvert.exporters.script import ScriptExporter
from notebook.utils import to_api_path


def script_post_save(model, os_path, contents_manager, **kwargs):
    """Save a copy of notebook to the corresponding language source script.

    For example, when you save a `foo.ipynb` file, a corresponding `foo.py`
    python script will also be saved in the same directory.

    However, existing config files I found online (including the one written in
    the official documentation), will also create an `Untitile.txt` file when
    you create a new notebook, even if you have not pressed the "save" button.
    This is annoying because we usually will rename the notebook with a more
    meaningful name later, and now we have to rename the generated script file,
    too!

    Therefore we make a change here to filter out the newly created notebooks
    by checking their names. For a notebook which has not been given a name,
    i.e., its name is `Untitled.*`, the corresponding source script will not be
    saved. Note that the behavior also applies even if you manually save an
    "Untitled" notebook. The rationale is that we usually do not want to save
    scripts with the useless "Untitled" names.
    """
    # only process for notebooks
    if model["type"] != "notebook":
        return

    script_exporter = ScriptExporter(parent=contents_manager)
    base, __ = os.path.splitext(os_path)

    # do nothing if the notebook name ends with `Untitled[0-9]*`
    regex = re.compile(r"Untitled[0-9]*$")
    if regex.search(base):
        return

    script, resources = script_exporter.from_filename(os_path)
    script_fname = base + resources.get('output_extension', '.txt')

    log = contents_manager.log
    log.info("Saving script at /%s",
             to_api_path(script_fname, contents_manager.root_dir))

    with io.open(script_fname, "w", encoding="utf-8") as f:
        f.write(script)

c.FileContentsManager.post_save_hook = script_post_save

要使用这个脚本，你可以将它添加到~/.jupyter/jupyter_notebook_config.py:)

请注意，您可能需要重新启动jupyter笔记本/实验室才能工作。

如果你想转换所有*。Ipynb文件从当前目录转移到python脚本，可以运行如下命令:

jupyter nbconvert --to script *.ipynb
