# a modified version of a simple eliza-like program
# based off of eliza1.py
#
# 1) greet user
# 2) get user's statement about life
# first exchange based on user's politeness
# 3) repeat until user leaves:
# 3.1) do a reflexion first to second person
# by replacing I by you, me by you,
# mine by yours, my by your, etc...
# and also 2nd to first person with correct grammar
# respond to aggressive user
# 3.2) figure out what to print
# if a family word was used, ask user about family
# if the sentence was reflected, then print it
# if the sentence contained no or never, then
# react to it
# otherwise, just a random canned sentence
#
from random import choice
# canned answers that the program will use to get the
# user to keep the conversation going...

"\nI see...",
"\nGo on...",
"\nTell me more",

# user is responding in the negative ("no", or "never")
cannedNegative = [ "\nMy, my, so negative!",
"\nNo?",
"\nIsn't that a bit strong?",
"\nReally?",
"\nYou really think so?",

"\nIs that a family trait?",
"\nTell me more about your family.",
"\nWhat do you think about your family?",
