本文实例讲述了Python生成密码库功能。分享给大家供大家参考,具体如下:
这个代码是将字符的所有组合添加到一个文件中,可以设置密码的最大长度,我这里设置的是8位,但是要有心里准备,生成的文件特别大。。。

#!/usr/bin/python import string letters = string.letters + string.digits + string.punctuation length = len (letters) fwrite = open ( "/tmp/genpass.txt" , "wt" ) fread = open ( "/tmp/genpass.txt" , "r" ) for num in xrange ( 8 ): for times in xrange (length * * num): line = fread.read(num + 1 ).rstrip() for letter in letters: fwrite.write(line + letter + "\n" ) fwrite.flush() fwrite.close() fread.close() |
希望本文所述对大家Python程序设计有所帮助。
