excel文件內容：

讀取excel：

# coding=utf-8
import xlrd
import sys

reload(sys)
sys.setdefaultencoding(‘utf-8‘)
import traceback


class excelHandle:
    def decode(self, filename, sheetname):
        try:
            filename = filename.decode(‘utf-8‘)
            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)
        sheet = rbook.sheet_by_name(sheetname)
        rows 
 
= sheet.nrows
        cols = sheet.ncols
        all_content = []
        for i in range(rows):
            row_content = []
            for j in range(cols):
                ctype = sheet.cell(i, j).ctype
                cell = sheet.cell_value(i, j)
                row_content.append(cell)
            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)

輸出：

[‘整形‘,‘175.0‘]
[‘字符串‘,‘最後的騎士‘]
[‘浮點型‘,‘6.23‘]
[‘日期‘,‘42909.6461574‘]
[‘空值‘,‘‘]

可以看到，數字一律按浮點型輸出，日期卻輸出成一串數字？！！

python讀取excel，數字都是浮點型，日期格式是數字的解決辦法
