Eliza Program

Version 1: Let's start with something very basic

# Eliza1.py
# D. Thiebaut
# A very short beginning program for Eliza



# --------------------------------------------------------------------------
# just print the string to the console
# will be transformed to something better later...
def myprint( string ):
    print( string )
    
# sayGoodBye
# say goodbye to the user.
def sayGoodBye( name ):
    myprint( "Good bye " + name )

# isGoodBye
# checks to see if what the user said is one of the keywords for
# ending the conversation.
def isGoodBye( userAnswer ):
    if userAnswer.lower().strip() in [ "bye", "goodbye", "ciao" ]:
        return True
    else:
        return False

def greetings():
    myprint( "Hello there!" )
    myprint( "What is your name?" )
    name = input( "> " )
    myprint( "Welcome " + name )
    return name

# --------------------------------------------------------------------------
# main function
# --------------------------------------------------------------------------                   
def main():

     # greet user and get her name
     userName = greetings()
     
     # conversation: get user input, and respond
     for i in range( 1000 ):

         # get user's statement
         userAnswer = input( "> " )

         # if it is a goodbye statement, exit the loop
         if isGoodBye( userAnswer ) == True:
             break

         # tell the user to continue speaking
         myprint( "Please tell me more..." )


     # if we're here, it's because the loop stopped.
     # say goodbye to the user
     sayGoodBye( userName )
            
         
main()

Version 2: Let's randomize the program's prompts

The new code is highlighted.

# Eliza2.py
# D. Thiebaut
# A very short beginning program for Eliza
# with random prompts from the program.
import random


# --------------------------------------------------------------------------
# just print the string to the console
# will be transformed to something better later...
def myprint( string ):
    print( string )
    
# sayGoodBye
# say goodbye to the user.
def sayGoodBye( name ):
    myprint( "Good bye " + name )

# isGoodBye
# checks to see if what the user said is one of the keywords for
# ending the conversation.
def isGoodBye( userAnswer ):
    if userAnswer.lower().strip() in [ "bye", "goodbye", "ciao" ]:
        return True
    else:
        return False

def greetings():
    myprint( "Hello there!" )
    myprint( "What is your name?" )
    name = input( "> " )
    myprint( "Welcome " + name )
    return name

# --------------------------------------------------------------------------
# main function
# --------------------------------------------------------------------------                   
def main():
     prompts = ["Please go on...", "Please tell me more...",
                "Interesting... Go on, please!", "Yes?  Really? Go on",
                "Weird... I'm not sure what to think of that..." ]
     
     # greet user and get her name
     userName = greetings()
     
     # conversation: get user input, and respond
     for i in range( 1000 ):

         # get user's statement
         userAnswer = input( "> " )

         # if it is a goodbye statement, exit the loop
         if isGoodBye( userAnswer ) == True:
             break

         # tell the user to continue speaking
         myprint( random.choice( prompts ) )

     # if we're here, it's because the loop stopped.
     # say goodbye to the user
     sayGoodBye( userName )
            
main()

Version 3: React to Negative User Answers

In this version the program will pick up on the user responding "No", or "Never", and respond differently if this is the case. The highlighted lines show the addition of new code.

# Eliza3.py
# D. Thiebaut
# A very short beginning program for Eliza
# with random prompts from the program.
import random


# --------------------------------------------------------------------------
# just print the string to the console
# will be transformed to something better later...
def myprint( string ):
    print( string )
    
# sayGoodBye
# say goodbye to the user.
def sayGoodBye( name ):
    myprint( "Good bye " + name )

# isGoodBye
# checks to see if what the user said is one of the keywords for
# ending the conversation.
def isGoodBye( userAnswer ):
    if userAnswer.lower().strip() in [ "bye", "goodbye", "ciao" ]:
        return True
    else:
        return False

# isNegativeAnswer
# returns True if user says a single word such as "no", or "never"
def isNegative( userAnswer ):
    if userAnswer.lower().strip() in [ "no", "never" ]:
        return True
    else:
        return False


def greetings():
    myprint( "Hello there!" )
    myprint( "What is your name?" )
    name = input( "> " )
    myprint( "Welcome " + name )
    return name.capitalize()

# --------------------------------------------------------------------------
# main function
# --------------------------------------------------------------------------                   
def main():
     prompts = ["Please go on...", "Please tell me more...",
                "Interesting... Go on, please!", "Yes? Really? Go on",
                "Weird... I'm not sure what to think of that..." ]

     promptsNegative = [ "Such strong words!", "Really?", "Why?",
                         "My, we are so negative today!", 
                         "You really think so?", "Why not?" ]
     
     # greet user and get her name
     userName = greetings()
     
     # conversation: get user input, and respond
     for i in range( 1000 ):

         # get user's statement
         userAnswer = input( "> " )

         # if it is a goodbye statement, exit the loop
         if isGoodBye( userAnswer ) == True:
             break

         # tell the user to continue speaking
         if isNegative( userAnswer ) == True:
             myprint( random.choice( promptsNegative ) )
         else:           
             myprint( random.choice( prompts ) )


     # if we're here, it's because the loop stopped.
     # say goodbye to the user
     sayGoodBye( userName )

Version 6: Adding Memory to Eliza

• To add memory to Eliza, we use the reflection, where the program recognizes answers of the form "I xxxx you" (where xxxx is some verb), and responds with "you xxxx me?", and takes this last sentence and adds it to the prompts list. This way, every so often, out of the blue, when the program does not recognize a family matter, or a reflection, or a negative comment, it will respond with "You xxxx me?"
