Python - how to generate wordlist from given characters of specific length

Question

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.

Answer 1

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)
