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

            sheetname = sheetname.decode('utf-8')
        except Exception:
            print traceback.print_exc()
        return filename, sheetname
 
    def read_excel(self, filename, sheetname):
        filename, sheetname = self.decode(filename, sheetname)
        rbook = xlrd.open_workbook(filename)

                cell = sheet.cell_value(i, j)

            all_content.append(row_content)
            print '[' + ','.join("'" + str(element) + "'" for element in row_content) + ']'
        return all_content
 
 
if __name__ == '__main__':
    eh = excelHandle()
    filename = r'G:\test\ctype.xls'
    sheetname = 'Sheet1'
    eh.read_excel(filename, sheetname)

 

(2) 稍微修改了一下，读取excel所有sheets的内容。
