python Spyder交互式输出

Question

最近我写了这段代码，试图找到一些计算抛物线积分的方法，但现在这对我来说没有任何问题，但关键是我写的代码没有给我任何输出，这很奇怪，我使用了spyder，代码如下：

def integrator(a,b,c):
#a,b and c are the factors of the quadratic
import numpy as np
delta=((b**2)-4*a*c)
answer1= (-b+delta)/2
answer2=(-b-delta)/2 
#it gets the answers of the quadratic eruation and uses them as the lower and upper bounds
if delta<=0:
return "this func has no real answer"
if delta==0:
return "this function has two equal answers"
return  answer1
else:
return answer1
return answer2
#it also calculate the answers of the quadratic equation too
integ_range=[]
for i in np.arange(answer1,answer2,0.01):
integ_range.append(i)
for i in integ_range:
heights=(a*(i**2))+(b*i)+c
sum1=sum(integ_range)    
integrate=sum1*0.01
return (integrate)
integrator(1,2,3)

我的代码的描述和未给定的输出

Answer 1

将变量分配给积分器为：

i=integrator(1,2,-3)
print(i)

应该可以
