Is there a way to use the dot syntax in Jupyter Notebook to call a function that was defined in a different notebook? For example, suppose I have a notebook “test.ipynb” containing a function called `square(x)`, and say we’ve imported test.ipynb using
```julia
using NBInclude
@nbinclude("test.ipynb")
```
Now that `test.ipynb` is imported, we can call `square()` just like a regular function, e.g. `square(x)`. But for bookkeeping purposes, I’d like to call `square` by referencing the notebook in which it was defined in, e.g. `test.square(x)`. Unfortunately I tried this and it didn’t work. Is there a similar way to do this?

nope, in order for `test.square()` to work, `test` must be a module. NBInclude doesn’t create one for you. and honestly that sounds like a bad idea. NBInclude at the moment works exactly like an `include()` with all the cell content stitched together in plain text.

Thanks for the answer. So I just have to create a module then…why would this be a bad idea?

the idea of single file as module (“automatically”, without having `module end` inside that file) sounds bad to me.
