How to use in realtime the output generated by a python script

[Mirco Piccin]

Hi everybody,

I've tried to run a python script that generates an output every 5 seconds (you can find it a the end of the message).

I've tried to run this script using nodered pythonshell, but it happens that the payload doesn't flow to the debug node until the end of the execution.

Is it possible to create a flow that allows to use every output generated by the scripts without waiting for the end of the execution?

I wasn't able to find any related post....

Can you help me?

Thanks everybody

Mirco

PS_

Example of the second python script:

from time import sleep

index = 0

print "Start "

while index < 5:

        print index

        index += 1

        sleep(5)

 

Example of the flow:

[{"id":"e0de42b1.049bd","type":"pythonshell in","z":"d8d38e5e.da6b2","name":"Continuous","pyfile":"/tmp/continuous.py","virtualenv":"","continuous":false,"x":331.5,"y":154,"wires":[["d1731e41.3f451"]]}]

If you use the built in exec node it says in the info

I don't know how you do that with that node - maybe need to contact the author direct...

Hi Dave,

thanks for the tip!

Now it's working like a charm! 

Here the updated flow:

[{"id":"d1731e41.3f451","type":"debug","z":"d8d38e5e.da6b2","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload","x":790,"y":220,"wires":[]},{"id":"f6620ca7.7b73","type":"exec","z":"d8d38e5e.da6b2","command":"python -u /tmp/continuous.py","addpay":false,"append":"","useSpawn":"true","timer":"","oldrc":false,"name":"","x":450,"y":340,"wires":[["d1731e41.3f451"],[],[]]},{"id":"94002ba2.6dd0a8","type":"inject","z":"d8d38e5e.da6b2","name":"","topic":"","payload":"","payloadType":"str","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":130,"y":240,"wires":[["f6620ca7.7b73"]]}]

thanks again
