編碼要求：
1、編碼中不出現“4”、“3”等不吉利數字，缺碼編號；
2、賣品第一個字母“L”表示禮盒裝、“B”表示標準裝。第二個字母是“A”到“Z”中的任意字母，可根據編碼需要任意選擇。四位數字為編號；
3、賣品與贈品區別在于：賣品以“L”或者“B”開頭，贈品以“ZL”或者“ZB”開頭。

例如：
賣品禮盒裝編碼  L-A0001  L-D0001等
賣品標準裝編碼  B-A0001  B-H0888等
贈品禮盒裝編碼  ZL-A0001  ZL-D0001等
贈品標準裝編碼  ZB-A0001  ZB-H0888等
 
其中如果有3個3的號碼也留下來，不用去掉。 本來想用js來實現，但如果那樣只能把生成的結果寫給頁面上了，而且刷新就沒了。

后來考慮了一下，選擇使用wxPython加上py2exe來做一個小的可執行文件，并把生成的編號放入txt文件中。 由于之前沒玩過wxPython，花了1個多小時終于搞定了！代碼如下：

                f.write(code)
                f.write('\n')
