1 2 3 4 5 6 7 8 9 10 11 12-13 def func (Coeff): sum= ' for key in coeff:sum=sum+ ' + ' +str (key) + ' * ' + ' x ' + ' * * ' +str (Coeff[key]) return sum[1:] from SymPy im Port * from sympy.core.sympify import sympifyerror expr = func ({2:0,3:1,4:2,5:7}) x = Symbol ("x") sexpr = sympify (expr) PR int diff (sexpr, x) print diff (sexpr, x). Subs (' x ', 3)

Use a dictionary to do this thing:

?

1 (2+3*x+4*x**2+7*x**3.7). diff (x). Subs ({x:3}). Evalf ()

I hope this article will help you with your Python programming.
