如何创建不包含单词中包含的前一个字母的单词？

Question

我看问题的角度停留在第一elif：你想

import random as rnd 

vowels="aeiou" 
consonants="bcdfghlmnpqrstvz" 
alphabet=vowels+consonants 

vocabulary={} 
index=0 
word="" 
positions=[] 
while index<5: 
    random_lenght=rnd.randint(2,5) 
    while len(word)<random_lenght: 
     random_letter=rnd.randint(0,len(alphabet)-1) 
     if len(word)==0: 
      word+=alphabet[random_letter] 
     elif random_letter != positions[-1] and len(word)>0: 
      if word[-1] not in vowels: 
       word+=alphabet[random_letter] 
      if word[-1] not in consonants: 
       word+=alphabet[random_letter] 
     elif random_letter == positions[-1]: 
      break   
     if random_letter not in positions: 
      positions.append(random_letter) 
    if word not in vocabulary: 
     vocabulary[index]=word 
     index+=1 
    word="" 

结果不能使我满意：

{0: 'in', 1: 'th', 2: 'cuu', 3: 'th', 4: 'vd'} 

任何帮助，将不胜感激。

你想应该是这样的（根据您的实现）什么：

import random as rnd 

vowels="aeiou" 
consonants="bcdfghlmnpqrstvz" 
alphabet=vowels+consonants 

vocabulary={} 
index=0 
word="" 
positions=[] 
while index<5: 
    random_lenght=rnd.randint(2,5) 
    while len(word)<random_lenght: 
     random_letter=rnd.randint(0,len(alphabet)-1) 
     if len(word) == 0: 
      word+=alphabet[random_letter] 
     elif random_letter != positions[-1] and len(word)>0: 
      if word[-1] not in vowels and alphabet[random_letter] not in consonants: 
       word+=alphabet[random_letter] 
      elif word[-1] not in consonants and alphabet[random_letter] not in vowels: 
       word+=alphabet[random_letter] 
     if random_letter not in positions: 
      positions.append(random_letter) 
    if word not in vocabulary: 
     vocabulary[index]=word 
     index+=1 
    word="" 

而另一个版本：

import string 
import random 

isVowel = lambda letter: letter in "aeiou" 

def generateWord(lengthMin, lengthMax): 
    word = "" 
    wordLength = random.randint(lengthMin, lengthMax) 
    while len(word) != wordLength: 
     letter = string.ascii_lowercase[random.randint(0,25)] 
     if len(word) == 0 or isVowel(word[-1]) != isVowel(letter): 
      word = word + letter 
    return word 

for i in range(0, 5): 
    print(generateWord(2, 5))
