Guys,

I have a Python program that should call a .bat program and receive a string as return.

But the feedback I'm getting is the own command of Python rather than the expected string return.

Why it is not returning the string should it?

The expected return should be: ABCD

But is returning: C:\Zope\2.11.4\Phyton>java -Djava.library.path="C:\Nitgen" -jar C:\Nitgen\Busca3-N_java.jar C:\Nitgen\arquivo.rec

Can someone help me?

Below the code:
