我是Python新手，所以我尝试使用以下代码调用ELM（position）函数来进行迭代：

def fitness(positon):
  for i in range(len(position[0])):
    acc[i] = ELM(position[i])
  return acc
acc = fitness(position)
print(acc)

但是当我运行时，出现如下错误：

> > --------------------------------------------------------------------------- TypeError                                 Traceback (most recent call last)
    > > <ipython-input-32-b5817c120096> in <module> 3     acc[i] = ELM(position[i]) 
4   return acc 
5 acc = fitness(position) 
6 print(acc)
