python: calling java program

Question

I have a tag cloud generator that I would like to call from my python program. How can I do it?

I run it in a batch file

java -jar ibm-word-cloud.jar -C configure.txt input.txt output.png

thanks for your help.

Answer 1

The subprocess module is now preferred over os.system(). A simple example, assuming run_prog.bat contains the command you need:

import subprocess
cmd = "run_prog.bat"
proc = subprocess.Popen(cmd)

Answer 2

You can use the os module:

import os
os.system('mybatchfile.bat')

or use the subprocess module
