将.ipynb文件导入到另外的文件中

在定义函数或者类的.ipyter文件的末尾加上

try:
    !jupyter nbconvert --to python ppp.ipynb  #ppp是文件的名称
except:
    pass

在需要导入到文件中：

import sys
#import os 
#os.getcwd()
sys.path.append("G:/Jupyter") #ppp文件的路径

from ppp import dd

方法二：

首先创建一个model.py文件，放在一个固定的位置

import io, os,sys,types
from IPython import get_ipython
from nbformat import read
from IPython.core.interactiveshell import InteractiveShell

class NotebookFinder(object):
    """Module finder that locates Jupyter Notebooks"""
    def __init__(self):
        self.loaders = {}
    def find_module(self, fullname, path=None):
        nb_path = find_notebook(fullname, path)
        if not nb_path:
            return
        key = path
        if path:
            #lists aren't hashable
            key = os.path.sep.join(path)
        if key not in self.loaders:
            self.loaders[key] = NotebookLoader(path)
        return self.loaders[key]

def find_notebook(fullname, path=None):
    """find a notebook, given its fully qualified name and an optional path
    This turns "foo.bar" into "foo/bar.ipynb"
    and tries turning "Foo_Bar" into "Foo Bar" if Foo_Bar
    does not exist.
    """
    name = fullname.rsplit('.', 1)[-1]
    if not path:
        path = ['']
    for d in path:
        nb_path = os.path.join(d, name + ".ipynb")
        if os.path.isfile(nb_path):
            return nb_path
        # let import Notebook_Name find "Notebook Name.ipynb"
        nb_path = nb_path.replace("_", " ")
        if os.path.isfile(nb_path):
            return nb_path
class NotebookLoader(object):
    """Module Loader for Jupyter Notebooks"""
    def __init__(self, path=None):
        self.shell = InteractiveShell.instance()
        self.path = path
    def load_module(self, fullname):
        """import a notebook as a module"""
        path = find_notebook(fullname, self.path)
        print ("importing Jupyter notebook from %s" % path)
        # load the notebook object
        with io.open(path, 'r', encoding='utf-8') as f:
            nb = read(f, 4)
        # create the module and add it to sys.modules
        # if name in sys.modules:
        # return sys.modules[name]
        mod = types.ModuleType(fullname)
        mod.__file__ = path
        mod.__loader__ = self
        mod.__dict__['get_ipython'] = get_ipython
        sys.modules[fullname] = mod
        # extra work to ensure that magics that would affect the user_ns
        # actually affect the notebook module's ns
        save_user_ns = self.shell.user_ns
        self.shell.user_ns = mod.__dict__

        try:
          for cell in nb.cells:
            if cell.cell_type == 'code':
                # transform the input to executable Python
                code = self.shell.input_transformer_manager.transform_cell(cell.source)
                # run the code in themodule
                exec(code, mod.__dict__)
        finally:
            self.shell.user_ns = save_user_ns
        return mod
sys.meta_path.append(NotebookFinder())

然后创建被调用的func.ipynb文件

def foo():
    print("123")

最后在调用func.ipynb的文件中加入二者的路径

再导入这两个文件，注意更改func.ipynb后要重启kernel
