python读取excel，数字都是浮点型，日期格式是数字的解决办法

读取excel：

# coding=utf-8import xlrdimport sysreload(sys)sys.setdefaultencoding('utf-8')import tracebackclass 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):                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_contentif __name__ == '__main__':    eh = excelHandle()    filename = r'G:\test\ctype.xls'    sheetname = 'Sheet1'    eh.read_excel(filename, sheetname)

输出：

['整形','175.0']['字符串','最后的骑士']['浮点型','6.23']['日期','42909.6461574']['空值','']['布尔型','1']

可以看到，数字一律按浮点型输出，日期却输出成一串小数？！布尔型输出0或1

 

代码稍做改动：来看一看表格的数据类型

        for i in range(rows):            row_content = []            for j in range(cols):                ctype = sheet.cell(i, j).ctype #表格的数据类型                print ctype,                cell = sheet.cell_value(i, j)                row_content.append(cell)            all_content.append(row_content)            print            print '[' + ','.join("'" + str(element) + "'" for element in row_content) + ']'

输出：

1 2['整形','175.0']1 1['字符串','最后的骑士']1 2['浮点型','6.23']1 3['日期','42909.6461574']1 0['空值','']1 4['布尔型','1']

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

 

所以，判断一下ctype，然后再做相应处理就可以了。

 

最终代码：

# coding=utf-8import xlrdimport sysreload(sys)sys.setdefaultencoding('utf-8')import tracebackfrom datetime import datetimefrom xlrd import xldate_as_tupleclass 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  # 表格的数据类型                cell = sheet.cell_value(i, j)                if ctype == 2 and cell % 1 == 0:  # 如果是整形                    cell = int(cell)                elif ctype == 3:                    # 转成datetime对象                    date = datetime(*xldate_as_tuple(cell, 0))                    cell = date.strftime('%Y/%d/%m %H:%M:%S')                elif ctype == 4:                    cell = True if cell == 1 else False                row_content.append(cell)            all_content.append(row_content)            print '[' + ','.join("'" + str(element) + "'" for element in row_content) + ']'        return all_contentif __name__ == '__main__':    eh = excelHandle()    filename = r'G:\test\ctype.xls'    sheetname = 'Sheet1'    eh.read_excel(filename, sheetname)

输出：

['整形','175']['字符串','最后的骑士']['浮点型','6.23']['日期','2017/23/06 15:30:28']['空值','']['布尔型','True']
