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()
