How to print to console in a Python WebJob on Microsoft Azure?

How do I print debug information from a Python script to the Azure WebJob Console?

I have successfully deployed a continuously running Python WebJob on Microsoft Azure, I have included my packages, and when the console showed some errors I've been able to fix them and re-upload through FTP.

Right now, the console (Azure WebJobs Dashboard) shows that my script is running.

[10/29/2015 10:42:53 > a19167: SYS INFO] Status changed to Starting [10/29/2015 10:42:53 > a19167: SYS INFO] Job directory change detected: Job file 'run.py' timestamp differs between source and working directories. [10/29/2015 10:42:58 > a19167: SYS INFO] Run script 'run.py' with script host - 'PythonScriptHost' [10/29/2015 10:42:58 > a19167: SYS INFO] Status changed to Running

However, my script is littered with print() statements which don't show. I have also tried sys.stdout.write() and sys.stderr.write() but they don't work either.

UPDATE: Print messages do show! They just appear in bulk, once every few hours...

To immediately see your log statements in the Azure WebJobs Dashboard, simply call sys.stdout.flush()

Flushing the console output makes sense after intializing the web job, and after processing a single task (e.g. processing a queue message).
