人机交互程序 python实现人机对话

自己随便写了一个人机交互的程序。不存在任何智能，只是可以识别姓名，可以记录对话内容，并保存等到下一次交互时加载。 （推荐面向对象版本）

# hello.py
# 这是老早写的。不过今天加入了Pickle，然后润色了一下。
# 可能有点无聊（不推荐使用） 

import pickle
import os.path 

def search(x, data):
  for k, d in enumerate(data):
    if x == d['name']:
      return k, d 

def save_data(A,pklname):
  with open(pklname, 'wb') as pkl:
    pickle.dump(A, pkl) 

def load_data(pklname):
  with open(pklname, 'rb') as pkl:
    return pickle.load(pkl) 

# communicating with computer
data=[] if not os.path.isfile('data') else load_data('data') 

while True:
  print('Welcome! [type "quit" if you want to quit.]')
  name=input('--What is your name?\n--')
  if name in {'quit','Quit','q','Q'}:
    print('[You quit]')
    break
  if not search(name, data):
    print('--Welcome, '+name+ '. I will remember you name.')
    d={'name':name,'age':0,'history':[]}
    data.append(d)
  else:
    print('--Hi, '+name+'. How I miss you.') 

  k, d=search(name, data)
  while d['age']==0:
    age=input('--How old are you?[I will repeat until you respond!]')
    try:
      if int(age)==0: continue
      d['age']=int(age); data[k]=d
    except:
      pass
  while True:
    y=input('--Chan I help you? [yes/no]')
    while not y:
      y=input('--Yes or no?')
    d['history'].append(y); data[k]=d
    if y in {'no','No','n','N'}:
      print('--%s.'%y)
      print('--Bye bye.')
      break
    elif y in {'yes','Yes','y','Y'}:
      print('--%s.'%y)
      print('I am pleased to serve you.')
    else:
      print('I am sorry. I can not understand what you said.')
      break     

# save data
y=input('--Do you want to save the data? [yes/no]')
while not y:
  y=input('--Yes or no?')
if y in {'no','No','n','N'}:
  print('--%s. [You say no.]'%y)
elif y in {'yes','Yes','y','Y'}:
  print('--%s. [the data is saved in file named "data".]'%y)
  save_data(data, 'data')
else:
  print('I am sorry. I can not understand what you said. data are not saved.') 

下面是hello.py的面向对象编程版本（推荐）

# hello.py 

import pickle
import os.path 

def search(x, data):
  for k, d in enumerate(data):
    if x == d['name']:
      return k, d 

class Hello:
  def __init__(self, name='', data=None):
    self.name = name
    self.data = data 

  def __getstate__(self):
    return self.data 

  def __setstate__(self, data):
    self.data = data 

  def mainloop(self): 

    while True:
      print('Welcome! [type "quit" if you want to quit.]')
      name=input('--What is your name?\n--')
      if name in {'quit','Quit','q','Q'}:
        print('[You quit]')
        break
      if not search(name, self.data):
        print('--Welcome, '+name+ '. I will remember you name.')
        d={'name':name,'age':0,'history':[]}
        self.data.append(d)
      else:
        print('--Hi, '+name+'. How I miss you.') 

      k, d=search(name, self.data)
      while d['age']==0:
        age=input('--How old are you?[I will repeat until you respond!]')
        try:
          if int(age)==0: continue
          d['age']=int(age); self.data[k]=d
        except:
          pass
      while True:
        y=input('--Chan I help you? [yes/no]')
        while not y:
          y=input('--Yes or no?')
        d['history'].append(y); self.data[k]=d
        if y in {'no','No','n','N'}:
          print('--%s.'%y)
          print('--Bye bye.')
          break
        elif y in {'yes','Yes','y','Y'}:
          print('--%s.'%y)
          print('I am pleased to serve you.')
        else:
          print('I am sorry. I can not understand what you said.')
          break 

    # save data
    y=input('--Do you want to save the data? [yes/no]')
    while not y:
      y=input('--Yes or no?')
    if y in {'no','No','n','N'}:
      print('--%s. [You say no.]'%y)
    elif y in {'yes','Yes','y','Y'}:
      print('--%s. [the data is saved in file named "data.pkl".]'%y)
      with open('data.pkl', 'wb') as fo:
        pickle.dump(self, fo)
    else:
      print('I am sorry. I can not understand what you said. data are not saved.')
    # communicating with computer 

try:
  with open('data.pkl', 'rb') as fo:
    hello=pickle.load(fo)
except:
  hello=Hello('ai',[]) 

hello.mainloop()
