modcell enables a Jupyter notebook cell as a module. It allows you to import a cell from another ipynb file by using modcell keyword.

modcell searches ipynb files registered in sys.path. modcell identifies # modcell comment in top of a cell and imports it as a module.

pip install modcell

You import the modecell in a file where you import a cell from another ipynb file.

For example in hello.ipynb:

import modcell as mods

import test_module as mod

x = mod.TestModule()
x.hello()

In test_module.ipynb:

# modcell
class TestModule:
    def __init__(self):
        pass

    def hello(self):
        print('Hello from TestModule')

Output:

Hello from TestModule

You can import a file from a sub-directory:

from mydir import sub_file as mod

x = mod.SubTestModule()
x.hello()

sub_file under mydir:

# modcell
class SubTestModule:
    def __init__(self):
        pass

    def hello(self):
        print('Hello from SubTestModule')

Output:

Hello from SubTestModule

Add the directory path to sys.path.

In sub_receiver.ipynb in parent directory:

import sys
sys.path.append('..')

import modcell as mods

import test_module as mod

x = mod.TestModule()
x.hello()

Output:

Hello from TestModule
