You're missing the to argument in the mail.EmailMessage() call. 您在mail.EmailMessage()调用中缺少to参数。
From google.appengine.api.mail module : 来自google.appengine.api.mail模块 ：
An EmailMessage can be built completely by the constructor:
EmailMessage(sender='sender@nowhere.com', to='recipient@nowhere.com', subject='a subject', body='This is an email to you').Send()
