I need to run a talend job outside of the talend studio. Is there any way to execute a talend job through python script ?
This is a common task and the following link gives detailed step by step procedure to create a .bat/.sh /jar.
https://community.talend.com/t5/Migration-Configuration-and/Exporting-a-Job-script-and-executing-it-outside-of-Talend-Studio/ta-p/21686
Once you create the job, then you can trigger it from python using subprocess.
import subprocess
subprocess.call(['(path)talendJob.jar'])
normally you can use any processmanagement tool to do that. For example
supervisor http://supervisord.org/. That's a processmanagement based
on python.

Is there any way to run python script on Windows VM continuously. This script should run even computer restarts automatically.
What I am doing right now?
I have a script called FooBar.py, it contains infinite while loop to execute main() function continuously. I am running this script on powershell.
What is problem in this approach?
Sometime this VM restarts automatically or powershell window may close accidentally. This kind of issues causing failure of script execution.
What I have tried so far?
I tried pythonw.exe instead of python.exe to run the script but this does not resolve my problem.
Is there any way to run FooBar.py script continuously, is there any way in windows scheduler to restart script execution even after computer restarts
You can use pm2 to schedule the startup of your script. You can find more information on how to use it here:
https://towardsdatascience.com/automate-your-python-script-with-pm2-463238ea0b65
you can use a module of python named "schedule"
and possibly you can run your code at whatever time you need !
use "pip install schecule" to download the library or module.
for an example i will leave you a pic how to use it.
enter image description here
i mean job in the picture is a function what you want to do.
if you want it to do for a time interval in secdonds then,you can use
schedule.every(#duration#).seconds.do(#declared function#)
thank you!
Create a task in windows scheduler with trigger On a schedule and with trigger option Repeat task every 1 min. Then in a Settings tab there is the dropdown menu If the task is already running, then the following rule applies: where you can choose Do not start a new instance.
I would like to run a python script every day in my EC2 Linux instance. My idea is to run my python script with time.sleep()at the end and detach the screen using screen Linux command. Is there a more efficient way to do this?
If you're looking to run a command at a specific time each day take a look at crontab. By using this you can set a schedule for when the script should run.
If you do have any output for the script then make sure that you pipe it to a log file.
You can use a cron job to execute your script at a given time. Take a look at a guide here.
I run my pywinauto test and I want the pytest to run after it. Now i run it with pycharm (Run->Edit configurations->Before launch:Activate tool window->Add run another configuration), but i want to run it with script.

In case1.py i tried:
subprocess.call(["python","tests\\test_xml_filename.py"])
os.system('C:\\Users\\user\\PycharmProjects\\pywinauto\\venv\\Scripts\\python C:\\Users\\user\\PycharmProjects\\pywinauto\\tests\\test_xml_filename.py')
but it still not work
It's not related to pywinauto. Just use subprocess.check_output(...).
output = subprocess.check_output("<your command>")
print(output)
Real-time passing stdout from child to parent process is not easy implementable. Why not using import script as a module and call dedicated function? One process, one stdout - it's much easier to maintain.
I am submitting a python script to condor. When condor runs it it gets
an import error. Condor runs it as
/var/lib/condor/execute/dir_170475/condor_exec.exe. If I manually copy
the python script to the execute machine and put it in the same place
and run it, it does not get an import error. I am wondering how to
debug this.
How can I see the command line condor uses to run it? Can the file
copied to /var/lib/condor/execute/dir_170475/condor_exec.exe be
retained after the failure so I can see it? Any other suggestions on
how to debug this?
You can simply run an interactive job (basically just a job with sleep or cat as command) and do ssh_to_job to run it.
Generally you need to set-up your python environment on the compute node, it is best to have a venv and activate it inside your start script.
I'm trying to automate some stuff I would otherwise have to do manually, so I can run one python script instead of taking a whole bunch of steps. I want to find a way to run a Talend job from the python script.
How do I accomplish this? Is it even possible?
Oops! sorry.
From the Studio, build the job to get an autonomous job you can launch from command line.
Extract the files from the generated archive.
Search for folder "script/yourJobname".
Check the syntax from one of the .bat or .sh depending of which one you prefer.
Launch the jar file using subprocess.call (or other way to execute a jar file from Python).
Hope this helps.TRF
As soon as you can run a Python script from command line, you should be able to run it from Talend using tSystem component.
