Python - 如何从特定长度的给定字符生成词表

问题描述

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?我尝试过 itertools.combinations_with_replacements 和 itertools.permutations，但没有帮助.他们没有它应该返回的所有单词列表.任何帮助将不胜感激.谢谢.

解决方案

使用 itertools.product:

>>>导入迭代工具>>>>>>chrs = 'abc'>>>n = 2>>>>>>对于 itertools.product(chrs, repeat=n) 中的 xs:... 打印 ''.join(xs)...aaAB交流电巴bb公元前钙CB抄送

从最小长度到最大长度获取单词:

chrs = 'abc'min_length, max_length = 2, 5对于范围内的 n(min_length，max_length+1):对于 itertools.product(chrs, repeat=n) 中的 xs:打印 ''.join(xs)

I want to perform a dictionary attack and for that I need word lists. How to generate word list from given characters of specific length ( or word length from min length to max length )? I have tried itertools.combinations_with_replacements and itertools.permutations, but it does not help. They does not have all the word lists that it should return. Any help will be greatly appreciated. Thank you.

解决方案

Use 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

To get word from min length to max length:

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)
