python - Python - 如何从特定长度的给定字符生成单词表

Question

我想执行字典攻击，为此我需要单词列表。如何从特定长度的给定字符（或从最小长度到最大长度的单词长度）生成单词列表？我试过itertools.combinations_with_replacementsand itertools.permutations，但它没有帮助。他们没有应该返回的所有单词列表。任何帮助将不胜感激。谢谢你。

Answer 1

使用itertools.product：

>>> import itertools
>>>
>>> chrs = 'abc'
>>> n = 2
>>>
>>> for xs in itertools.product(chrs, repeat=n):
...     print ''.join(xs)
...
aa
ab
ac
ba
bb
bc
ca
cb
cc

获取从最小长度到最大长度的单词：

chrs = 'abc'
min_length, max_length = 2, 5    
for n in range(min_length, max_length+1):
    for xs in itertools.product(chrs, repeat=n):
        print ''.join(xs)

Answer 2

这是一个幼稚的实现：

list='abcdefg'
depth=8

def generate(l,d):
  if d<1:
    return
  for c in l:
    if d==1:
      yield c
    else:
      for k in generate(l,d-1):
        yield c+k

for d in range(1,depth):
  for c in generate(list,d):
    print c

我还没有足够的声誉来发表评论，因此，根据上面的 itertools 示例制作一个完整的列表：

import itertools
chrs='abc'
n=6
for i in range(1,n):
  for xs in itertools.product(chrs, repeat=i):
    print ''.join(xs)

这样，您的列表中就有长度为 1 到 n 的所有单词。

Answer 3

from itertools import product

def allwords(chars, length):
    for letters in product(chars, repeat=length):
        yield ''.join(letters)

def main():
    letters = "abc"
    for wordlen in range(3, 5):
        for word in allwords(letters, wordlen):
            print(word)

if __name__=="__main__":
    main()

返回

aaa
aab
aac
aba
abb

...

ccbc
ccca
cccb
cccc
