Python单词接龙小程序

偶然间阅读资料发现Linux发行版内置了英语词典，随手用Python写个小程序进行词语接龙

规则：用户给出第一个词，系统根据结尾随机给出一个相同开头的词，如此反复

用户词不得重复，单词表中也不含缩写符号的词

代码如下

#!/usr/bin/python3
from random import sample

file = open('/usr/share/dict/words')
word = [x[:-1] for x in file.readlines() if "'" not in x]
file.close()
# [word.remove(x) for x in word if x[-1]=='s' and x[:-1] in word]
begin = False
com = ''
used = []
num = 0

while True:
    while True:
        usr = input('Your word =')
        if usr not in word:
            print('Word',usr,'not found!')
            continue
        elif usr in used:
            print('You have used',usr,'before!')
            continue
        else:
            break
    if begin and usr[0] != com[-1]:
        print('Must begin with',com[-1])
        continue
    ans = [x for x in word if x[0]==usr[-1]]
    com, = sample(ans,1)
    num += 1
    print('[Your turn %d'%num, com)
    used.append(usr)
    begin = True

愉快的玩耍吧！实测s开头的特别多……

体验不佳可打开第7行注释过滤各类复数词，对应初始化时间也会随之增加。
