This is my code
这是我的代码
14 def sum(output):
15 result = 0
16 for x, w in zip(output[0], output[1]):
17 result+=w*np.exp(-((((b-a)/2.0)*x)+((a+b)/2.0))**2)
18 pprint(w*exp(-((((b-a)/2.0)*x)+((a+b)/2.0))**2))
19 return ((b-a)/2.0)*result
For this code if i call a function sum my output on terminal will print:
对于此代码，如果我调用函数sum，我的终端输出将打印：
0.548543700179284
0.6
0.692267362730138
0.0
0.252818105473090
0.6
but if
但如果
14 def sum(output):
15 result = 0
16 for x, w in zip(output[0], output[1]):
17 result+=w*np.exp(-((((b-a)/2.0)*x)+((a+b)/2.0))**2)
18 return ((b-a)/2.0)*result
19
20 pprint(w*np.exp(-((((b-a)/2.0)*x)+((a+b)/2.0))**2))
It will print a beautiful equation(I mean pprint() it's work!).
它将打印一个漂亮的等式（我的意思是pprint（）它的工作！）。
Why the first code can not print a beautiful equation like the second code?
为什么第一个代码不能像第二个代码那样打印漂亮的等式？

It is hard to say without more context, but probably because w and x are both defined both inside and outside of your function sum().
没有更多的上下文很难说，但可能因为w和x都在函数sum（）的内部和外部定义。
Also note that the two lines are not the same:
还要注意两条线不一样：
pprint(w*exp(-((((b-a)/2.0)*x)+((a+b)/2.0))**2))
pprint(w*np.exp(-((((b-a)/2.0)*x)+((a+b)/2.0))**2))
