AttributeError的：「功能」對象有沒有屬性「四」在Python

Question

from scipy import linalg 
from scipy.integrate import quad 
import numpy as np 


a = integrate.quad(lambda x: x**2, 0, 4.5) 
print(a) 

---

AttributeError       Traceback (most recent call last) 
<ipython-input-132-c7f6592004af> in <module>() 
     2 from scipy.integrate import quad 
     3 import numpy as np 
----> 4 a = integrate.quad(lambda x: x**2, 0, 4.5) 
     5 
     6 

AttributeError: 'function' object has no attribute 'quad' 

我不知道發生什麼事，任何人都可以幫助我嗎？謝謝！

Answer 1

該代碼輸入quad;您無需限定它：

from scipy.integrate import quad # <---- 
.... 

a = quad(lambda x: x**2, 0, 4.5)
