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:
```python
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".

我看到你尝试使用scipy.integrate模块中的quad函数进行数值积分。然而,你的代码似乎有问题。函数"fun46"定义不正确。在行尾应该有一个冒号,并且乘法运算符应该是"*"而不是"np.pi"。这是修正后的代码:
```python
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)
```
在这段代码中,quad函数用于对函数"fun46"在从-1到1的范围内进行积分。积分的结果存储在变量"I"中,估计的误差存储在变量"error"中。
