How to get errors in Python subprocess created by java

Question

I start the python process by java Runtime.getRuntime().exec("python pythonCode.py") method,

I want to get to know about are there are any errors in python programm and what are those,can i do that?

There are a boundless number of errors that could come from a python program. If its well written, a non-zero exit code is the basic indicator and other information may be on stderr, stdout or log files. Its like any other program, nothing special about python. — tdelaney, Jun 16 '20 at 04:52
can I get stderr file to the java programm and inteprete its meaning? I tried ' c=sys.stderr s="%s"%c.errors print("%s"%c.errors)' in python code and I got 98 when I read by java code how to interprete it? — Sandaru Akalanka, Jun 16 '20 at 04:56
I'm not a java guy. Since this isn't really a python program it may be best to remove python and subprocess tags. Let the java folks focus on it. — tdelaney, Jun 16 '20 at 05:13

Please try the following suggestion

Try to write some logs like success.log or failure.log in your python process and after Runtime is ran check if success or failure log is there.
If the process is failed parse the failure log to get the root cause.

hope this will help your question
