请问各位老师,这种情况我该怎么办：

Question

def getState(data, t, n):
    d = t - n + 1
    # block = data[d:t + 1] if d>= 0 else -d * [data[0]]+ data[0:t+1]
    block = data[d:t + 1]
    #res = [0 for x in range(0, len(n))]
    res = []
    for i in range(n - 1):
        res.append(block[i + 1]-block[i])
        #print("res=",res[i])
    return np.array([res])

之后它说我：    res.append(block[i + 1]-block[i])
IndexError: list index out of range
Episode1

 

然后我把代码改成了：

def getState(data, t, n):
    d = t - n + 1
    # block = data[d:t + 1] if d>= 0 else -d * [data[0]]+ data[0:t+1]
    block = data[d:t + 1]
    res = [0 for x in range(0, len(n))]
    #res = []
    for i in range(n - 1):
        res.append(block[i + 1]-block[i])
        #print("res=",res[i])
    return np.array([res])

然后它说我：  res = [0 for x in range(0, len(n))]
TypeError: object of type 'int' has no len()

那么请问各位老师我到底该怎么改

Answer 1

你改成 [0 for x in range(0, n)]
