Used at my school to execute shell scripts.

shell2.py

# Python 2 Shell Executor

import socket, sys
from subprocess import call

def main():
    print "\nPython 2 Shell Executor"
	ip = socket.gethostbyname(socket.gethostname())
	print "Your internal IP:", ip, "\n"

	print "[1] Execute Command\n[2] Exit"
	choice = raw_input("\n> ")

	if choice is "1":
		get_input()
	elif choice is "2":
		sys.exit()
	else:
		main()

def get_input():
	command_name = raw_input("\ncommand_name> ")
	command_args = raw_input("command_args> ")

	if not command_args:
		call(command_name, shell = True)
		main()
	else:
		call([command_name, command_args])
		main()

main()

shell3.py

import socket, sys

def main():
    print("\nPython 3 Shell Executor")
	ip = socket.gethostbyname(socket.gethostname())

	print("[1] Execute Command\n[2] Exit")
	choice = input("\nchoice> ")

	if choice is "1":

	elif choice is "2":

	else:

def get_input():
	command_name = input("command_name> ")
	command_args = input("command_args> ")

	if not command_args:

	else:

main()
