Help on function find_executable in module distutils.spawn:

find_executable(executable, path=None)
      Try to find 'executable' in the directories listed in 'path' (a
      string listing directories separated by 'os.pathsep'; defaults to
      os.environ['PATH']).  Returns the complete filename or None if not
      found.

py> distutils.spawn.find_executable("sc")
'C:\\WINDOWS\\system32\\sc.exe'
