我目前正在做 GCSE 案例研究，我需要代碼方面的幫助。我正在嘗試為一組數據創建一個二維數組。這是代碼：#ArrayDays = ["Mon1","Tue1","Wed1","Thu1","Fri1","Mon2","Tue2","Wed2","Thu2","Fri2","Mon3","Tue3","Wed3","Thu3","Fri3","Mon4","Tue4","Wed4","Thu4","Fri4"]Buses = ["A","B","C","D","E","F"]BusData = [ [0,0,0,2,2], [4,0,3,4,-2], [-5,0,0,3,4], [-1,8,1,1,-2],  #Bus A            [0,1,0,0,1], [2,0,0,0,0], [1,0,0,0,2], [0,0,1,0,0],   #Bus B            [2,0,-1,-1,-2], [-2,-3,-1,0,0], [-2,0,1,1,1], [1,-1,-1,2,-2] #Bus C            [1,0,0,0,0], [0,0,0,0,0], [2,0,0,0,0], [0,0,0,0,0], #Bus D            [-1,-1,-1,-2,-4], [-10,-2,0,0,0], [0,1,2,-3,1], [1,3,-1,0,0]  #Bus E            [0,-5,-5,-5,-4], [-3,-5,0,0,0], [0,-2,-3,1,1], [1,0,0,-2,-5] ] #Bus Ffor i in BusData:    count = 0    for x in i:        if x < 0:            count +=1    print("Bus {} was late {} times".format(Buses[BusData.index(i)], count))所以在我運行它之后，我得到這個錯誤：因此，第 7 行（即#Bus D）中似乎存在錯誤，我不明白為什么？如果有人能用簡單的東西（GCSE 級別）回答我或修改我的代碼，那將不勝感激，因為距離考試時間不多了！
