Call Perl script from Python

Question

I've got a Perl script that I want to invoke from a Python script. I've been looking all over, and haven't been successful. I'm basically trying to call the Perl script sending 1 variable to it, but don't need the output of the Perl script, as it is a self contained program.

What I've come up with so far is:

var = "/some/file/path/"
pipe = subprocess.Popen(["./uireplace.pl", var], stdin=subprocess.PIPE)
pipe.stdin.write(var)
pipe.stdin.close()

Only just started Python programming, so I'm sure the above is total nonsense. Any help would be much appreciated.

Answer 1

Just do:

var = "/some/file/path/"
pipe = subprocess.Popen(["perl", "uireplace.pl", var])

Answer 2

If you just want to open a pipe to a perl interpreter, you're on the right track. The only thing I think you're missing is that the perl script itself is not an executable. So you need to do this:

var = "/some/file/path/"
pipe = subprocess.Popen(["perl", "./uireplace.pl", var], stdin=subprocess.PIPE)
pipe.stdin.write(var)
pipe.stdin.close()
