Python2将函数输出列表转换为可调用数组

Question

我有一个程序，我整个周末一直在工作，它包含正确的输出，但它输出一个不可调用的列表，我需要能够从中构建一个图。如何修改列表以使其可调用？

def conv395(x,h):
        #Function to convolve x input signal and h impulse response

    M = len(h)-1
    L = len(x)
    Ly = M+L
    LOL = []

    def ConV(x,h,n):
        y = (h[m]*x[(n-1)-m])
        return (y)

    for n in range(0,Ly+1):

        mx = n-L+1

        if mx < 1:
            n = n+1
            #print("SPACE")
            Y1 = 0

            if n <= M+1:

                L1 = []
                for m in range(n):
                    #print(n) 

                    y = ConV(x,h,n)
                    Y1 = y + Y1

                L1.append(Y1)
                LOL.append(str(L1))
                #print Y,     

    ###LOL = np.int32(LOL)


            if n > M+1:
                #print("Space")
                L2 = []
                N = n-1
                n = M+1
                Y2 = 0

                for m in range(n):                                     
                    y2 = h[m]*x[(N-m)] 
                    Y2 = Y2 + y2
                L2.append(Y2)
                LOL.append(str(L2))



        if mx > 1:
               #print("space")  
               L3 = []   
               if n > M+1:
                   Y3 = 0

               for m in range(n-L,M+1):
                   y3 = h[m]*x[m-(n-L)]
                   Y3 = Y3 + y3
               L3.append(Y3)
               LOL.append(str(L3))


    return(LOL)             


h = [1,2,-1,1]
x = [1,1,2,1,2,2,1,1] 

Y = conv395(x,h)
print(callable(Y))

OUTPUT显示列表不可调用，输出看起来像这样[＆＃39; [1]＆＃39;，＆＃39; [3]＆＃39;，＆＃39; [ 3]＆＃39;，＆＃39; [5]＆＃39;，＆＃39; [3]＆＃39;，＆＃39; [7]＆＃39;，＆＃39; [4] ＆＃39;，＆＃39; [3]＆＃39;，＆＃39; [3]＆＃39;，＆＃39; [0]＆＃39;，＆＃39; [1]＆＃ 39] 我已经尝试过在互联网上找到的各种形式的转换，它不会让步。建议？
