Python：集成了100个函数和集成变量

Question

我想计算表格的积分：。

我很努力在Python中实现这一点。有没有一种程序化的方式来实现这一点？我试着用几个for循环做这个，但是我被卡在错误SystemError: too many statically nested blocks上。

fs = {} 
for i in range(100): 
    fs[i] = lamda x: x*i 

for x1 in np.arange(0,1,.01): 
    for x2 in np.arange(0,1,.01): 
     .... 
      for x100 in np.arange(0,1,.01): 
      for i in range(100): 
       exec("summ+= fs[i](x%i"%i) 

Answer 1

当然是慢： 的 “对于i在范围（100）”（1）部分达到100 * 100 * 100 * ... * 100（100“* 100的）= 100^100;和人们说n^2是坏的... 反正我会这样做的：

- Put 100 values initialized with 0 into a list. 
- for i = 0 to 100^100: 
    - go through the list and use the k-th value as the parameter for the k-th function. do the summing thing 
    - Add 0.1 to the n-th value in the list; 
    if this value is now == 1; set it to 0 and go to the (n+1)-th value and repeat this procedure until you reach the end of the list or one value is < 1. 
    Start with the first value in the list. 
now you have your sum.
