In addition to what others have written in this thread, there is yet
another potential confusion, stemming from such data types as elements of
polynomial rings. E.g.
sage: R.=QQ[]
sage: f=2*x*y-5
sage: type(f)
shows that f here is neither a python function nor a symbolic expression.
Although
I think you got it, but I'm just adding this below in case someone else is
also interested:
Here, this sequence defines a symbolic x, and that function f, and then
checks the types
x = var('x')
f=lambda x: x*sin(x)
type(f)
type(f(x))
and f(x) is still a symbolic expression.
Now we change x to b

I assumed that SageMath converts the functions into symbolic expressions.
If I enter the following it will work:
f=lambda x: x*sin(x)
diff(f(x),x)
def g(x):
return x*sin(x)
diff(g(x),x)

So, can you copy/paste us an example? It does work, if that small
python-function is evaluated and returns a
I'm aware of the difference between the two approaches in vanilla Python, I
was just trying to figure out if SageMath treats the two differently. You
can integrate and differentiate both types of functions in SageMath as well
as use them for solving differential equations.

This is actually a pure Python question, and the answer is yes. Technically:
def f1(x):
