我知道这是一个老话题了。我也遇到过同样的问题，想通过命令行将.pynb文件转换为.py文件。

我的搜索把我带到了ipynb-py-convert

通过以下步骤，我能够得到.py文件

安装pip Install ipynb-py-convert 通过命令提示符进入ipynb文件所在目录 输入命令

ipynb-py-convert你的文件名。ipynb YourFilename.py

如:。ipynb-py-convert getting-started-with-kaggle-titanic-problem。ipynb getting-started-with-kaggle-titanic-problem.py

上面的命令将创建一个名为“YourFileName.py”的python脚本，根据我们的示例，它将创建一个“getting-start -with-kaggle-titanic-problem.py”文件

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 

我已经构建了一个函数来实现这一点。用户不需要安装任何东西就可以使用它。

# A short routine to convert a Jupyter Notebook to a Python file

import json

def ipynb_to_py(input_ipynb_file,output_py_file=None):
    """
    Generate a Python script (.py) that includes all source code from the input Jupyter notebook (.ipynb).
    
    The user can input a Jupyter Notebook file from the current working directory or from a path.
    
    If the name for output Python file is not specified, 
    the output file name will copy the file name of the input Jupyter Notebook, 
    but the file exention will be changed from ".ipynb" chanegd to ".py".
    And the output Python file will be saved at the same directory of the input Jupyter Notebook.
    For example:
    ipynb_to_py("test-jupyternotebook.ipynb")
    ipynb_to_py("./test-input-dir/test-jupyternotebook.ipynb")
    
    The user can also specify an output file name that ends with ".py".
    If the output file name is provided, but no path to output file is added, 
    the file will be saved at the current working directory.
    For example:
    ipynb_to_py("test-jupyternotebook.ipynb","test1.py")
    ipynb_to_py("./test-input-dir/test-jupyternotebook.ipynb","test2.py")
        
    The user can save out the file at a target directory by adding a path to the output file.
    For example: 
    ipynb_to_py("test-jupyternotebook.ipynb","./test-outputdir/test3.py")
    ipynb_to_py("./test-input-dir/test-jupyternotebook.ipynb","./test-output-dir/test4.py")
    
    This function does not edit or delete the original input Jupyter Notebook file.
    
    Args:
    -----
        input_ipynb_file: The file name string for the Jupyter Notebook (ends with ".ipynb")
        output_py_file (optional): The file name for Python file to be created (ends with ".py"). 
    
    Returns:
    --------
        A Python file containing all source code in the Jupyter Notebook.
        
    Example usages:
    ---------------
        ipynb_to_py("test-jupyternotebook.ipynb")
        ipynb_to_py("./test-input-dir/test-jupyternotebook.ipynb")

%notebook foo。ipynb magic命令将当前IPython导出到“foo.ipynb”。

更多信息输入%笔记本?

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:

我知道这是一个老话题了。我也遇到过同样的问题，想通过命令行将.pynb文件转换为.py文件。

我的搜索把我带到了ipynb-py-convert

通过以下步骤，我能够得到.py文件

安装pip Install ipynb-py-convert 通过命令提示符进入ipynb文件所在目录 输入命令

ipynb-py-convert你的文件名。ipynb YourFilename.py

如:。ipynb-py-convert getting-started-with-kaggle-titanic-problem。ipynb getting-started-with-kaggle-titanic-problem.py

上面的命令将创建一个名为“YourFileName.py”的python脚本，根据我们的示例，它将创建一个“getting-start -with-kaggle-titanic-problem.py”文件
