如何在兩個“for”函數下在python上打印任何數學計算？

Question

我是 python 新手，我不明白為什么這段代碼不起作用。 在我嘗試校准 LED 的代碼中，樓層號 + 單元號應分配給 LED 的數量。

floors = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20
unitperfloor = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10


for i in floors:
    for j in unitperfloor:
        numberofpixel = unitperfloor[j] + ((floors[i] - 1) * 92)
        print("floor:" + str(floors[i]) + " unit: " + str(unitperfloor[j]) + " = " + str(numberofpixel))

我試圖只打印i ， j並且我看到它正常工作。 但是當我添加這個numberofpixel計算時， numberofpixel循環了 1 次。

Answer 1

floors=[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20]
unitperfloor=[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]


for i in floors:
    for j in unitperfloor:
        numberofpixel = j + ((i- 1) * 92)
        print("floor:{} unit: {} = {}".format(i,j,numberofpixel))

For 獲取列表元素的值，而不是列表的索引。

floors=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20
unitperfloor=1, 2, 3, 4, 5, 6, 7, 8, 9, 10


for i in range(len(floors)):
    for j in range(len(unitperfloor)):
        numberofpixel = unitperfloor[j] + ((floors[i] - 1) * 92)
        print("floor:" + str(floors[i]) + " unit: " + str(unitperfloor[j]) + " = " + str(numberofpixel))
