import win32com.client as win32
import xlrd
 
outlook = win32.Dispatch('outlook.application')
mail = outlook.CreateItem(0)
receivers = ['**;**']
cc='test02@163.com'+';'+'test03@alibaba.com'
mail.To = receivers[0]
mail.cc=cc
mail.Subject = '附件为明细，请查收！'
workbook = xlrd.open_workbook('C:\\Users\\Administrator\\Desktop\\报表\\线上指标考核\\数据源\\5月\\5.1\\发邮件\\成交明细5.4.xlsx')
mySheet = workbook.sheet_by_index(0)
 
nrows = mySheet.nrows
content = []
for i in range(nrows):
    ss = mySheet.row_values(i)
    content.append(ss)
    print(content)
    Truecontent = str(content)
 
mail.Body = "附件为明细，请查收！"
mail.Attachments.Add('C:\\Users\\Administrator\\Desktop\\报表\\考核\\数据源\\5月\\5.1\\发邮件\\明细5.4.xlsx')
mail.Send()
