Running sage script from python script

[Aleksandra Pietrzkiewicz]

Hi, 

I have an issue with compatibility, I think. 

I want to call some functions from sage script (but saved as .py) from another python3 script. 

so my matrix.py is like: 

#!/usr/bin/sage 

from sage.all import *

def my_field(dim): 

   return GF(2**dim, 'a')

#and more here - like creating special matrixes

and I want to call it from python3 script (smth.py) like: 

import matrix.py

M = gen_matrix(my_field(4))

but I do always get some issues, like: ModuleNotFoundError or alike, because I start with:

python3 smth.py and_some_args.

Did someone ever had some similar issue? 

I'd appreciate some help.

This would be fine to run as ./matrix.py (assuming your Sage is indeed
/usr/bin/sage, else you need to replace
this with the correct path).

If you just want to import is as a Python module then you don't need
the 1st #! line at all.

this most likely means that python3 does not know anything about Sage,
i.e. the latter has its own,
different, installation of Python3, which you can start as

sage --python
