最近我寫了這段代碼，試圖找到一些方法來計算拋物線的積分，但現在對我來說這不是任何問題，但關鍵是我寫的代碼沒有給我任何輸出，這很奇怪我使用 spyder 和代碼如下：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)我的代碼的描述和未給出的輸出
