Question

How can write a python script which will execute some perl scripts in a gui and shouldn't be post processed....?

Answer 1

Not sure if I understood your question correctly -

You could try the subprocess.call() method something like this

var = "/your/file/path"
retcode = subprocess.call(["./yourperlscript.pl", var])
if retcode == 0:
    print("Passed!")
else:
    print("Failed!")

In case you are looking for something different please comment appropriately.

I want to update the results of the perl script on gui....which should be in runtime.

Not able to understand, please provide an example (may be step by step) so that it is clear what you are trying to do and what is expected.
