The ability to expand an expression containing unknown functions, about some point, is obviously very valuable, and it is nice that this is possible using SymPy, however if I expand f(x) about 0 I get this:
f(0) + x*Subs(Derivative(f(_x), _x), _x, 0) + x**2*Subs(Derivative(f(_x), (_x, 2)), _x, 0)/2 + O(x**3) Is there any way to reduce that to something neater and more like textbook maths such as f(0)+x*f`(0)+x**2*f```(0)/2 + O(x**3) I chose f` rather than f' because as far as I know, the '`' character is not used in Python. Outputting the expression as Latex cleans it up a bit, but it is still not as neat as the usual notation for the derivative of a function notation.
