One 、 needed python modular

itemtools A brief understanding of the module is as follows ：

impor itertools

# product(*iterables,repeat=n)
# 1) When repeat=1 when , Is equivalent to ‘abcd’ and xy Are combined , But the sequence can only be ‘abcd’ stay ‘xy’ front 
'''''''''
ite = itertools.product('abcd','xy',repeat=1)
list1 = list(ite)

print(f' The length is ：{len(list1)}')  #  The length is ：8
print(list1)    # [('a', 'x'), ('a', 'y'), ('b', 'x'), ('b', 'y'), ('c', 'x'), ('c', 'y'), ('d', 'x'), ('d', 'y')]
'''''''''

# 2） When repea=2 when , Is equivalent to ‘abcd’ A copy of , hold ‘abcd’ and ‘abcd’ Are combined 
'''''''''
ite1 = itertools.product('abcd',repeat=2)
list2 = list(ite1)

print(f' The length is ：{len(list2)}')  #  The length is ：16
print(list2)    # [('a', 'a'), ('a', 'b'), ('a', 'c'), ('a', 'd'), ('b', 'a'), ('b', 'b'), ('b', 'c'), ('b', 'd'), ('c', 'a'), ('c', 'b'), ('c', 'c'), ('c', 'd'), ('d', 'a'), ('d', 'b'), ('d', 'c'), ('d', 'd')]
'''''''''

The following methods will also be used os、sys modular , You can learn from Baidu by yourself ;

Two 、 scripting

1. Simple password dictionary generation script

'''''''''

explain ：

1）words Followed by the characters you want to randomly arrange and combine ;

2） The generated permutation and combination passwords will be saved in the locally generated pass.txt in

3）repeat The following number is the password that generates several digits

'''''''''

import itertools as ite
words = '[email protected]$%^&*'
r = ite.product(words,repeat=3)
dic = open('pass.txt','a')
for i in r:
    dic.write(''.join(i))
    dic.write(''.join('\n'))

dic.close()

2. Simple password dictionary generation script optimization  

'''''''''

explain ：

1） After executing the script, enter the characters and password digits that need to be combined randomly ;

2） The generated permutation and combination passwords will be saved in the locally generated pass.txt in

3）repeat The following number is the password that generates several digits

'''''''''

import itertools as ite
import sys,os

words = sys.argv[1]
num = int(sys.argv[2])
path = str(os.path)
r = ite.product(words,repeat=num)

with open('pass.txt','a') as f:
    for i in r:
        f.write(''.join(i))
        f.write(''.join('\n'))
print(' Generated by '+words+' Randomly composed '+str(num)+' Bit password dictionary ！')
print(' Password dictionary name ：pass.txt')
print(' Dictionary path ：',path)

 perform ：
 Execute at the terminal ：python .\test.py abc 3

 Generated by abc Randomly composed 3 Bit password dictionary ！
 Password dictionary name ：pass.txt
 Dictionary path ： <module 'ntpath' from 'D:\\Tools\\Python\\install\\lib\\ntpath.py'>

3、 ... and 、 Advantages of the second method

# 1） After optimization, there is no need to modify the combined characters from the script 
# 2） The optimized code is more concise 

#  Beginners write their own , Understand that there will be better methods and optimization .
