问题描述

运行IPython笔记本时,我试图获取当前的笔记本名称.我知道我可以在笔记本顶部看到它.

I am trying to obtain the current NoteBook name when running the IPython notebook. I know I can see it at the top of the notebook. What I am after something like

currentNotebook = IPython.foo.bar.notebookname()

我需要在变量中获取名称.

I need to get the name in a variable.

推荐答案

如前所述,您可能真的不应该这样做,但是我确实找到了一种方法.尽管这是一个令人发指的骇客,所以请不要完全依赖于此:

As already mentioned you probably aren't really supposed to be able to do this, but I did find a way. It's a flaming hack though so don't rely on this at all:

import json
import os
import urllib2
import IPython
from IPython.lib import kernel
connection_file_path = kernel.get_connection_file()
connection_file = os.path.basename(connection_file_path)
kernel_id = connection_file.split('-', 1)[1].split('.')[0]

# Updated answer with semi-solutions for both IPython 2.x and IPython < 2.x
if IPython.version_info[0] < 2:
    ## Not sure if it's even possible to get the port for the
    ## notebook app; so just using the default...
    notebooks = json.load(urllib2.urlopen('http://127.0.0.1:8888/notebooks'))
    for nb in notebooks:
        if nb['kernel_id'] == kernel_id:
            print nb['name']
            break
else:
    sessions = json.load(urllib2.urlopen('http://127.0.0.1:8888/api/sessions'))
    for sess in sessions:
        if sess['kernel']['id'] == kernel_id:
            print sess['notebook']['name']
            break

我更新了答案,以包含至少在一个简单的测试中即可在IPython 2.0中运行"的解决方案.如果有多个笔记本连接到同一内核等,则可能不能保证给出正确的答案.

I updated my answer to include a solution that "works" in IPython 2.0 at least with a simple test. It probably isn't guaranteed to give the correct answer if there are multiple notebooks connected to the same kernel, etc.
