我想實現的算法,但要得到一個錯誤,我不知道是什麼原因:獲取類型錯誤:列表索引必須是整數,而不是元組
size = len(data)
total = sum(data)
barray = [[False for x in range(int(size+1))] for x in range(int((total/2)+1))]
for x in range(0,size):
barray[0][x] = True
for x in range(1,int(total/2)):
barray[x][0] = True
for i in range(1,int(total/2)):
for j in range(1,size):
barray[i,j] = (barray[i, j - 1] or barray[i - data[j - 1], j - 1]) if data[j-1] <= i else barray[i, j - 1]
return barray[int(total/2),size]
錯誤:

TypeError: list indices must be integers, not tuple
' 'B [I,J]'!= 'B [i] [j]''使用時numpy的(或類似的)陣列 – jonrsharpe
這(在OPS)語法是唯一正確的。 –
