You might want to try just putting the code in a some text file whose
extension is ".sage". For example, I put the following code in a file
called "demo.sage", not "demo.py":
[mv...@sage ~]$ cat demo.sage
x = var("x")
f(x)= 8
print f.derivative()
type(f)
Then I use Sage to execute the script like so:
[mv...@sage ~]$ sage demo.sage
x |--> 0
