将Jupyter实验室笔记本转换为脚本,而不添加批注和单元格之间的新行

到目前为止,Jupyter默认不提供此类功能。不过,您可以通过使用几行代码(例如,从python文件中手动删除空行和注释)。

def process(filename):
    """Removes empty lines and lines that contain only whitespace, and
    lines with comments"""

    with open(filename) as in_file, open(filename, 'r+') as out_file:
        for line in in_file:
            if not line.strip().startswith("#") and not line.isspace():
                out_file.writelines(line)

现在,只需在从jupyter笔记本转换的python文件上调用这个函数。

process('test.py')

另外,如果您希望一个实用程序函数将jupyter笔记本转换为没有注释和空行的python文件,那么您可以在下面建议的函数中包含上述代码。 here :

import nbformat
from nbconvert import PythonExporter

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

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

    with open(out_file, 'w+') as out_file:
        out_file.writelines(source)

    # include above `process` code here with proper modification
