Streaming values in a python script to a wep app | 36,671,291 | 1 | 0 | 63 | 0 | python,azure,web-applications,azure-webjobs | You have two main options:
You can have the WebJobs write the values to a database or to Azure Storage (e.g. a queue), and have the Web App read them from there.
Or if the WebJob and App are in the same Web App, you can use the file system. e.g. have the WebJob write things into %home%\data\SomeFolderYouChoose, and hav... | 0 | 1 | 0 | 0 | 2016-04-16T20:42:00.000 | 2 | 1.2 | true | 36,669,500 | 0 | 0 | 1 | 2 | I have a python script that runs continuously as a WebJob (using Microsoft Azure), it generates some values (heart beat rate) continuously, and I want to display those values in my Web App.

Certificate Error while Deploying python code in Google App Engine | 36,673,729 | 1 | 0 | 97 | 0 | python,google-app-engine | Upgrading Python to 2.7.8 or later versions fixed the issue.
EDIT:
Also check if you are using google app engine SDK 1.8.1 or later version. As of version SDK 1.8.1 the cacerts.txt has been renamed to urlfetch_cacerts.txt.
