Python|使用字典从字符集中提取单词

给定单词，任务是使用定义的字典从一组字符中提取不同的单词。
方法：
Python在其语言中定义了一个内置模块enchant来处理与单词相关的某些操作。在提到的方法中，使用了以下方法。

• check() :它检查字符串字符串单词则返回 true，否则返回 false。
• permutations(str_arr, str_len) :它根据提到的字符串长度提供字符串的组合。

有可能enchant()模块可能不存在，因此可以使用pip3 install enchant安装它。

下面是上述方法的Python代码实现。

# importing libraries
import keyword
import enchant
from itertools import permutations 
  
d = enchant.Dict("en_US")
  
words = []
perm_word = []
  
# character combination to 
# list down all the words
str_arr = "star"
  
# Getting the string length to use it in the loop. 
str_len = 4
print("Length of the string is : ", str_len )
  
while str_len > 1 :
      
    if str_len == len(str_arr):
        perm = list(permutations(str_arr))
        str_len = str_len -1
          
        for i in list(perm):
            words =''.join(i)
              
            if d.check(words):
                perm_word.append(words)
                print ( words + " is an English words")
        print ("perm_word", perm_word)
          
    elif str_len > 1:
        perm = list(permutations(str_arr, str_len))
        str_len = str_len -1
          
        for i in list(perm):
            words =''.join(i)
              
            if d.check(words):
                perm_word.append(words)
                print ( words + " is an English word")
        print ("perm_word", perm_word)
          
    else:
        str_len = 0
