How To Run Python In Java

How to run file*.py* in your Java program without using Jython? For example: I have JButton and I want to run python script when I click on the JButton. What should I put in Actio

Solution 1:

You need to have the python interpreter installed in the machine where you want to do that and call this interpreter as an external command from Java.

Look at this question to know more about how perform that call: Execute external program in java

From there:

String[] params = new String [2];
params[0] = PATH2_YOUR_PYTHON_SETUP + "python.exe";
params[1] = PATH2_YOUR_PYTHON_SCRIPT;
Runtime.getRuntime().exec(params);

Additionally, you can use the returned Process object from exec to interact with your script input/output.
