Python：无法在AWS Lambda中导入模块应用程序

Question

我的app.zip文件的根目录中有文件app.py。 根据处理程序配置，还正确定义了函数处理程序（ lambda_handler ）： app.lambda_handler

但是，我收到错误消息： Unable to import module 'app': No module named app

我哪里做错了？

我的剧本：

尝试检查日志输出。 它会为您提供比上述错误更多的信息。

最后，请记住，您需要使用Python 2语法，像这样替换调用：

按print(number_of_words) print number_of_words print(number_of_words)
