如前所述，您可能真的不应该能够执行此操作，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：

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，则可能无法保证给出正确的答案。
