python之发送邮件

　　项目需要，需要自动生成PDF测试报告。经过对比之后，选择使用了reportlab模块。 项目背景：开发一个测试平台，供测试维护测试用例，执行测试用例，并且生成测试报告（包含PDF和excel），将生成的测试报告以邮件的形式发送相关人。

　　发送邮件代码如下：

# 邮件发送

    def __init__(self):
        self.smtpSender = 'xxx@xxx.com'
        self.smtpAddr = 'smtp.exmail.qq.com'

    def __replaceformat__(self, formator, **args):
        for k in args.keys():
            rk = "{" + k + "}"
            if formator.__contains__(rk):
                formator = formator.replace(rk, str(args[k]))
        return formator
