python读取excel中单元格的内容返回的有5种类型，即上面例子中的ctype:

ctype： 

0   empty

1   string

2   number

3   date

4   boolean

5   Error

12 class excelHandle:

14         try:
15             filename = filename.decode(\'utf-8\')
16             sheetname = sheetname.decode(\'utf-8\')
17         except Exception:

27         all_content = []

51     eh.read_excel(filename, sheetname)

 

(2) 稍微修改了一下，读取excel所有sheets的内容。
