Sympy理智-express（x + 3）** 6/6

Question

I'm not able to do this and I'm not sure why? When I enter:

x = symbols('x')
exp = Rational((x+3)**6, 6)

I'm given a Type_Error.

---

This stems from trying to integrate (x + 3)**5 and expecting the result of (x+3)**6 / 6

Answer 1

The type Rational in Sympy represents a rational number, not a polynomial over the rational numbers; see the documentation . Simply use division instead:

p = (x + 3) ** 6 / 6
