在 96 孔板中有 8 列（A、B、...）和 12 行（01 ... 12）；所以盘子看起来像这样：
A01 A02 ... A12
B01 B02 ... B12
C01 ...
...
H01 ..
目前，我已将这些板块标识为：
1 2 3 4 ... 12
13 14 15 ...24
..
84 ... 96
如何编写函数wellnumber2wellidentifier将数字索引转换为顶部使用的格式？例如，well1会返回A01，well13会返回B01。
哦，当然，去让它从 1 开始，你为什么不...
'ABCDEFGH'[(num - 1) // 12] + '%02d' % ((num - 1) % 12 + 1,)
