当然，一个拼音可以对应多个诗歌。
诗歌接龙
读取pickle文件，编写程序，以exe文件形式运行该程序。
为了能够在编译形成exe文件的时候不出错，我们需要改写xpinyin模块的_init_.py文件，将该文件的全部代码复制至mypinyin.py，并将代码中的下面这句代码


data_path = os.path.join(os.path.dirname(os.path.abspath(__file__)),
        'Mandarin.dat')


改写为


data_path = os.path.join(os.getcwd(), 'Mandarin.dat')


这样我们就完成了mypinyin.py文件。
接下来，我们需要编写诗歌接龙的代码（Poem_Jielong.py），完整代码如下：


import pickle
from mypinyin import Pinyin
import random
import ctypes

STD_INPUT_HANDLE = -10
STD_OUTPUT_HANDLE = -11
STD_ERROR_HANDLE = -12

FOREGROUND_DARKWHITE = 0x07 # 暗白色
FOREGROUND_BLUE = 0x09 # 蓝色
FOREGROUND_GREEN = 0x0a # 绿色
FOREGROUND_SKYBLUE = 0x0b # 天蓝色
FOREGROUND_RED = 0x0c # 红色
FOREGROUND_PINK = 0x0d # 粉红色
FOREGROUND_YELLOW = 0x0e # 黄色
FOREGROUND_WHITE = 0x0f # 白色

std_out_handle = ctypes.windll.kernel32.GetStdHandle(STD_OUTPUT_HANDLE)

# 设置CMD文字颜色
def set_cmd_text_color(color, handle=std_out_handle):
 Bool = ctypes.windll.kernel32.SetConsoleTextAttribute(handle, color)
 return Bool

# 重置文字颜色为暗白色
def resetColor():
 set_cmd_text_color(FOREGROUND_DARKWHITE)

# 在CMD中以指定颜色输出文字
def cprint(mess, color):
 color_dict = {
     '蓝色': FOREGROUND_BLUE,
     '绿色': FOREGROUND_GREEN,
     '天蓝色': FOREGROUND_SKYBLUE,
     '红色': FOREGROUND_RED,
     '粉红色': FOREGROUND_PINK,
     '黄色': FOREGROUND_YELLOW,
     '白色': FOREGROUND_WHITE
     }
 set_cmd_text_color(color_dict[color])
 print(mess)
 resetColor()

color_list = ['蓝色','绿色','天蓝色','红色','粉红色','黄色','白色']

# 获取字典
with open('./poemDict.pk', 'rb') as f:
 poem_dict = pickle.load(f)

#for key, value in poem_dict.items():
 #print(key, value)

MODE = str(input('Choose MODE(1 for 人工接龙, 2 for 机器接龙): '))

while True:
 try:
  if MODE == '1':
   enter = str(input('\n请输入一句诗或一个字开始：'))
   while enter != 'exit':
    test = Pinyin().get_pinyin(enter, tone_marks='marks', splitter=' ')
    tail = test.split()[-1]
    if tail not in poem_dict.keys():
     cprint('无法接这句诗。\n', '红色')
     MODE = 0
     break
    else:
     cprint('\n机器回复：%s'%random.sample(poem_dict[tail], 1)[0], random.sample(color_list, 1)[0])
     enter = str(input('你的回复：'))[:-1]

   MODE = 0

  if MODE == '2':
   enter = input('\n请输入一句诗或一个字开始：')

   for i in range(10):
    test = Pinyin().get_pinyin(enter, tone_marks='marks', splitter=' ')
    tail = test.split()[-1]
    if tail not in poem_dict.keys():
     cprint('------>无法接下去了啦...', '红色')
     MODE = 0
     break
    else:
     answer = random.sample(poem_dict[tail], 1)[0]
     cprint('（%d）--> %s' % (i+1, answer), random.sample(color_list, 1)[0])
     enter = answer[:-1]

   print('\n（*****最多展示前10回接龙。*****）')
   MODE = 0

 except Exception as err:
  print(err)
 finally:
  if MODE not in ['1','2']:
   MODE = str(input('\nChoose MODE(1 for 人工接龙, 2 for 机器接龙): '))


现在整个项目的结构如下（Mandarin.dat文件从xpinyin模块对应的文件夹下复制过来）：

切换至该文件夹，输入以下命令即可生成exe文件：


pyinstaller -F Poem_jielong.py



本项目的诗歌接龙有两种模式，一种为人工接龙，就是你先输入一句诗或一个字，然后就是计算机回复一句，你回复一句，负责诗歌接龙的规则；另一种模式为机器接龙，就是你先输入一句诗或一个字，机器会自动输出后面的接龙诗句（最多10个）。
先测试人工接龙模式：

再测试机器接龙模式：
