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）

      with open('data.pkl', 'wb') as fo:

hello.mainloop()
