Code and Solve an Integration function On Python

Question

Can someone please help me with coding and solving this integration
function f(x)=x^2e^−xsin(x)  on Python programming language. xMin =1,
xMax =3, N = 200

I have tried all I could but I only got no output when i run the
python compiler. For example I wrote the following code based on the
information I found from web sources.

a=1
b=3
N=200
def integrate(a, b, N):
    def f(x):
       return x**2*math.exp(-x)*math.sin(x)
    value=0
    value2=0
    for n in range(1,N+1):
        value += f(a+((n-(1/2))*((b-a)/N)))
    v alue2=((b-a)/N)*value
    return value2

With no outcome. Could you please help. I am stuck here, I am  just a beginner.

Answer 1

Could you link your code using the icon circle/plus? As posted, you never called your intgegrate function nor asked for any output.

Answer 2

I figured I'd update from what you posted so:
