Fortran magic
Compile and import symbols from a cell with Fortran code, using f2py.
Attention!
I am looking for collaborators to maintain this project. If you are interested, please open an issue (or PRs) with your proposals for improvements and volunteer to be a maintainer.
The contents of the cell are written to a .f90 file in the directory IPYTHONDIR/fortran using a filename with the hash of the code. This file is then compiled. The resulting module is imported and all of its symbols are injected into the user's namespace.

Install
You can install or upgrade via pip
pip install -U fortran-magic
Basic usage
Once it's installed, you can load it with %load_ext fortranmagic.
Then put your Fortran code in a cell started with the cell magic %%fortran. For example:
In[2]: %load_ext fortranmagic
In[3]: %%fortran
subroutine f1(x, y, z)
real, intent(in) :: x,y
real, intent(out) :: z
z = sin(x+y)
end subroutine f1
Every symbol is automatically imported. So the subroutine f1 is already available in your python session as a function:
In[4]: f1(1.0, 2.1415) Out[4]: 9.26574066397734e-05
