How to import from another ipython-notebook?

To import functions or variables from one IPython notebook into another, you can use the %run magic command or the %load magic command.

  1. Using %run Magic Command:

    In the notebook where you want to import the code, use %run followed by the path to the notebook you want to import.

    %run /path/to/another_notebook.ipynb

    This will execute the code in the specified notebook in the current namespace, and you'll have access to its functions and variables.

  2. Using %load Magic Command:

    If you want to load specific code from another notebook into the current notebook, you can use %load.

    %load /path/to/another_notebook.ipynb

    This will load the content of the specified notebook into the cell where the %load command is used. You can then run the cell to execute the loaded code.

Keep in mind that when using %run, all the code in the specified notebook will be executed, which may have side effects such as defining variables and functions in the current namespace.

If you want a more modular and organized approach, you may consider converting the code in the other notebook into a Python module (.py file) and then importing that module using import in your current notebook.

For example, suppose you have a notebook named another_notebook.ipynb. You can convert it to a Python script using the following command in the terminal:

jupyter nbconvert --to script another_notebook.ipynb

This will create a file named another_notebook.py. You can then import functions and variables from this script in your current notebook using regular Python imports:

from another_notebook import my_function, my_variable

Remember to adjust the file paths based on your specific directory structure.

Examples

  1. "Import functions from another IPython notebook"

    %run /path/to/another_notebook.ipynb

    Description: Uses the %run magic command to execute code from another IPython notebook, making its functions and variables available in the current notebook.

  2. "Import specific functions from another notebook"

    %run -i /path/to/another_notebook.ipynb
from another_notebook import specific_function

    Description: Imports only specific functions from another notebook after running it using %run.

  3. "Import all variables from another IPython notebook"

    %store -r -d data

    Description: Uses %store to import all variables from another notebook into the current one.

  4. "Import classes from another IPython notebook"

    %run /path/to/another_notebook.ipynb
from another_notebook import ClassName

    Description: Imports a class from another notebook using %run and the standard import statement.

  5. "Import IPython notebook as a module"

    import ipynb
from ipynb.fs.full.another_notebook import function_name

    Description: Utilizes the ipynb module to import functions or variables from another IPython notebook.

  6. "Import variables with %store from another IPython notebook"

    %store -r -d variable_name

    Description: Imports a specific variable from another notebook using %store.

  7. "Import functions using import_ipynb"

    !pip install import_ipynb
import import_ipynb
import another_notebook

    Description: Installs the import_ipynb package and uses it to import functions or variables from another IPython notebook.

  8. "Import functions from another notebook using importnb"

    !pip install importnb
import importnb
with importnb.Notebook():
    import another_notebook

    Description: Installs the importnb package and uses it to import functions or variables from another notebook.

  9. "Import functions from another notebook using nbimporter"

    !pip install nbimporter
import nbimporter
with nbimporter.Notebook():
    from another_notebook import function_name

    Description: Installs the nbimporter package and uses it to import functions or variables from another notebook.

  10. "Import functions from another notebook using importnb"

    !pip install importnb
import importnb
with importnb.Notebook():
    from another_notebook import function_name

    Description: Installs the importnb package and uses it to import functions or variables from another notebook.
