將孔數轉換爲96孔板上的標識符

Question

在96孔板中有8列（A，B，...）和12行（01 ... 12）; 所以板看起來是這樣的：

A01 A02 ... A12 
B01 B02 ... B12 
C01 ... 
... 
H01 .. 

目前我已經確定板塊爲：

1 2 3 4 ... 12 
13 14 15 ...24 
.. 
84 ...  96 

我如何可以編寫一個函數wellnumber2wellidentifier的數值指標轉換成在頂部使用的格式？例如，井1將返回A01井13將返回B01。

Answer 1

哦，當然，去讓它1基於你爲什麼不......

'ABCDEFGH'[(num - 1) // 12] + '%02d' % ((num - 1) % 12 + 1,) 

Answer 2

以@Ignacio巴斯克斯 - 艾布拉姆斯的進一步回答了幾步。 。 。這裏是兩種方法：

幾乎任何尺寸的機架（列x欄）

1. 工作
2. 轉換爲和從數字位置從A1，B1等風格良好位置。
