from scipy.integrate import quad def fun46(y): return 2np.pi(1-y**2) I = I

I see that you are trying to use the quad function from the scipy.integrate module to perform numerical integration. However, there seems to be an issue with your code. The function "fun46" is not defined correctly. It should have a colon at the end of the line, and the multiplication operator should be "*" instead of just "np.pi". Here's the corrected code:

from scipy.integrate import quad
import numpy as np

def fun46(y):
    return 2 * np.pi * (1 - y**2)

I, error = quad(fun46, -1, 1)

In this code, the quad function is used to integrate the function "fun46" over the range from -1 to 1. The result is stored in the variable "I", and the estimated error is stored in the variable "error".
