如何使用排列从输入中查找所有可能的单词？ [关闭]

Question

我正在为我的编程课做一个项目，这是我正在努力的 5 件事。感谢您的帮助！

1. 有效单词列表将在 words.txt 中提供
2. 要求只接受 2-8 个字母组合的输入
3. 例如。输入将是“马球”
4. 从 words.txt 中查找此输入的所有可能的有效单词

5. 可能的结果，“poo”“pool”“loop”“polo”

   import random
   import itertools
   
   file_name='words.txt'
   DEBUG=True
   
   def load_words():
       try:
           f=open(file_name,'r')
           str1=f.read()
           f.close()
       except:
           print('Problem opening the file',file_name)
       list1=[]
       list1=str1.split()
       if DEBUG:
           length=len(list1)
           print('Number of words is',length)
           print(list1[0],list1[length//2],list1[-1])
           for i in range(10):
               print(list1[random.randint(1,length)])
       return(list1)
   
   def is_valid(str1,list1):
       valid=False
       count=0
       if str1 in list1:
           valid=True
       return valid
   
   def generate(letters):
       print(len(letters))
       count=1
       answers=[]
       for length in range(2,len(letters)+1):
           for x in itertools.permutations(letters,length):
               word=''
               for let in x:
                   word+=let
               print(word)
               if is_valid(word):
                   answers.append(word)
               count+=1   
           print(count,x)
           return(answers)
   
   def main():
       words=load_words()
       generate('abcde')
       guess=input('Check a word')
       if is_valid(guess.upper(),words):
           print(guess,'is a real word')
       else:
           print(guess,'is not a real word')
   
   main()

就错误而言 print(list1[random].randint(1,length)) 应改为 print(list1[random.randint(1,length)])
