• How to get path to the installed GIT in Python?

  - by Vladimir Prudnikov

  I need to get a path to the GIT on Max OS X 10.6 using Python 2.6.1 into script variables. I use this code for that: r = subprocess.Popen(shlex.split("which git"), stdout=subprocess.PIPE) print r.stdout.read() but the problem is that output is empty (I tried stderr too). It works fine with another commands such as pwd or ls. Can anyone help me with that?

• Why would it be necessary to subclass from object in Python?
