从笔记本本身中保存笔记本的副本

Question

我想从笔记本的单元格内保存笔记本的副本(或将其重命名)。

最好不要有太多的JavaScript。实际上，我猜这种形式的东西应该可以用

from IPython.display import display_html
display_html("script>Jupyter....???...()</script>")

这是一个仅用Python编写的解决方案。notebook_path函数来自P.Toccaceli在How do I get the current IPython Notebook name上的解决方案。

from notebook import notebookapp
import urllib
import json
import os
import ipykernel
from shutil import copy2

def notebook_path():
    """Returns the absolute path of the Notebook or None if it cannot be determined
    NOTE: works only when the security is token-based or there is also no password
    """
    connection_file = os.path.basename(ipykernel.get_connection_file())
    kernel_id = connection_file.split('-', 1)[1].split('.')[0]

    for srv in notebookapp.list_running_servers():
        try:
            if srv['token']=='' and not srv['password']:  # No token and no password, ahem...
                req = urllib.request.urlopen(srv['url']+'api/sessions')
            else:
                req = urllib.request.urlopen(srv['url']+'api/sessions?token='+srv['token'])
            sessions = json.load(req)
            for sess in sessions:
                if sess['kernel']['id'] == kernel_id:
                    return os.path.join(srv['notebook_dir'],sess['notebook']['path'])
        except:
            pass  # There may be stale entries in the runtime directory 
    return None


  def copy_current_nb(new_name):
    nb = notebook_path()
    if nb:
        new_path = os.path.join(os.path.dirname(nb), new_name+'.ipynb')
        copy2(nb, new_path)
    else:
        print("Current notebook path cannot be determined.")

然后，只需使用copy_current_nb('Save1')在同一目录中创建一个名为Save1.ipynb的副本。
