记录下自己学习python的过程

这个是进行备份后，并发送邮件附件进行保存的功能。 相对来说比较简陋，可以自行修改，简略步骤，美化过程等。

示例代码：

#!/usr/bin/env python
    # -*- coding:utf-8 -*-
    
    import os
    import time
    import smtplib
    import string
    from email.header import Header
    from email.mime.multipart import MIMEMultipart
    from email.mime.text import MIMEText
    
    def sendMail(datas):
        # 定义相关数据,请更换自己的真实数据
        smtpserver = 'smtp.163.com'
        sender = 'to_darcy@163.com'
        # receiver可设置多个，使用“,”分隔
        receiver = 'todarcy@163.com'
        username = 'to_darcy@163.com'
        password = '123456'
    
        msg = MIMEMultipart()
        for i in datas:
            att = MIMEText(open(i, "rb").read(), "base64", "utf-8")
            att["Content-Type"] = "application/octet-stream"
            i = i.replace("/tmp/data_backup/", "")
            att["Content-Disposition"] = 'attachment; filename= %s ' %i
            msg.attach(att)
    
        receivers = receiver
        toclause = receivers.split(',')
        msg['To'] = ",".join(toclause)
        # 添加主题，不然提示554 DT:SPM错误
        msg['SUBJECT'] = "数据库备份成功"
    
        # 登陆并发送邮件
        smtp = smtplib.SMTP()
        try:
            # # 打开调试模式
            # smtp.set_debuglevel(1)
            smtp.connect(smtpserver)
            smtp.login(username, password)
            smtp.sendmail(sender, receivers, msg.as_string())
        except:
            print("邮件发送失败！！")
        else:
            print("邮件发送成功")
        finally:
            smtp.quit()
    
    
    def mysqldump():
        USER = 'root'
        PASSWORD = '123456'
        MYSQLDUMP = 'docker exec -i  mysql mysqldump '
        DATABASES = ['yao','icaesee']
        TO_BACKUP_DIR="/tmp/data_backup/"
        lists = [];
    
        for  DB in  DATABASES:
            Backupfile_name = TO_BACKUP_DIR + DB +  '-' + time.strftime('%Y-%m-%d') + '.sql'
            Gzipfile_name = Backupfile_name + '.gz'
            if os.path.isfile(Gzipfile_name):
                print Gzipfile_name + " is already backup"
            else:
                Backup_command = MYSQLDUMP  + ' -u' +  USER  + ' -p' + PASSWORD  + " " +  DB  + ' >'  +  Backupfile_name
                print Backup_command
                # break
                if os.system(Backup_command) == 0:
                    lists.append(Gzipfile_name)
                else:
                    print "Fail"
                # 打包压缩成.gz
                GZIP_command = "gzip " +  Backupfile_name
                if os.system(GZIP_command) == 0:
                        print 'Successful gzip' + Backupfile_name +  ' to ' + Gzipfile_name
                else:
                        print 'Fail gzip' + Backupfile_name +  ' to ' + Gzipfile_name
        if len(lists) > 0:
            sendMail(lists)
    
    mysqldump()
