I also used eval but yours is so much cleaner! Thanks!

L = []
for _ in range(0, int(raw_input())):
    user_input = raw_input().split(' ')
    command = user_input.pop(0)
    if len(user_input) > 0:
        if 'insert' == command:
            eval("L.{0}({1}, {2})".format(command, user_input[0], user_input[1]))
        else:
            eval("L.{0}({1})".format(command, user_input[0]))
    elif command == 'print':
        print L
    else:
        eval("L.{0}()".format(command))
