import pickle,random

a=open('lexicon-luke','rb')

successorlist=pickle.load(a)

a.close()

def nextword(a):

   if a in successorlist:

      return random.choice(successorlist[a])

   else:

      return 'the'

speech=''

while speech!='quit':

   speech=raw_input('>')

   s=random.choice(speech.split())

   response=''

   while True:

      neword=nextword(s)

      response+=' '+neword

      s=neword

Hi,

I got the above code from:

https://stackoverflow.com/questions/5306729/how-do-markov-chain-chatbots-work

I am getting following error:

Traceback (most recent call last):
  File "/home/zulfi/PycharmProjects/chatbot/MarkovBot.py", line 13, in <module>
    speech=raw_input('>')
NameError: name 'raw_input' is not defined

Somebody please guide me how to define raw_input(...)?

You should be well aware by now, after months spend on writing Python, how to solve such basic issues..

Simply enter error or warning message in e.g. Google search engine.. e.g.

https://www.google.com/search?q=NameError%3A+name+'raw_input'+is+not+defined

and we see the list of people who had exactly the same issue as you in the past.

Write it down: use Google search engine.

That's what programmers do all day long.

Immediately you have answers, without having to wait until somebody will answer your question on the forum here.

Hi,

Thanks a lot.

 

I thought raw_input(..) is a user-defined function. Thanks it worked by changing raw_input(...) to input(...).
