遵循前面的例子，但是使用了新的nbformat lib版本:

import nbformat
from nbconvert import PythonExporter

def convertNotebook(notebookPath, modulePath):

  with open(notebookPath) as fh:
    nb = nbformat.reads(fh.read(), nbformat.NO_CONVERT)

  exporter = PythonExporter()
  source, meta = exporter.from_notebook_node(nb)

  with open(modulePath, 'w+') as fh:
    fh.writelines(source.encode('utf-8'))

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 

遵循前面的例子，但是使用了新的nbformat lib版本:

def convertNotebook(notebookPath, modulePath):

  with open(notebookPath) as fh:
    nb = nbformat.reads(fh.read(), nbformat.NO_CONVERT)

  source, meta = exporter.from_notebook_node(nb)

  with open(modulePath, 'w+') as fh:
    fh.writelines(source.encode('utf-8'))

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

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

下面的示例将一个名为a_notebook的Iron Python Notebook转换为。ipynb转换到一个名为a_python_script.py的python脚本中，省略带有关键字remove的单元格，我手动将其添加到我不想在脚本中结束的单元格中，省略了可视化和其他步骤，一旦我完成了笔记本，我不需要由脚本执行。

import nbformat as nbf
from nbconvert.exporters import PythonExporter
from nbconvert.preprocessors import TagRemovePreprocessor

with open("a_notebook.ipynb", 'r', encoding='utf-8') as f:
    the_notebook_nodes = nbf.read(f, as_version = 4)

trp = TagRemovePreprocessor()

trp.remove_cell_tags = ("remove",)

pexp = PythonExporter()

pexp.register_preprocessor(trp, enabled= True)

the_python_script, meta = pexp.from_notebook_node(the_notebook_nodes)

with open("a_python_script.py", 'w', encoding='utf-8') as f:
    f.writelines(the_python_script)
