Use the subprocess module:
http://docs.python.org/library/subprocess.html

untested, but should work:

subprocess.Popen([r'c:\shake91.txt', 'param1', 'paramN-1', 'paramN'])

if you want to communicate with the process you can add ,
stdout=subprocess.PIPE, stdin=subprocess.PIPE) to the function call.

Check the docs for more info.
