生成随机密码这件事情用python来干确实相当的方便，优美的string方法加上choice简直是绝配
make_password.py

###简单几行代码执行即可生成记不住的字符串###$ python make_passwd.py DLrw9EiT Qs4Wm84q RQwl4L2L u9g0LgwW jHPtYdyU ...$ python make_passwd.py DLrw9EiT Qs4Wm84q RQwl4L2L u9g0LgwW jHPtYdyU ...

代码如下——注释比代码长

生成一些人似乎能好记一些的密码(Qs4Wm84q这种密码似乎除了复制粘贴没有别的选择，话说前年我使用shell生成的类似的密码给ldap做默认密码，我当时公司就真有员工把这样的密码背下来了，现在想想真心是厉害~~~)。

##这样看起来是比上面的好记一点了吧，但需要提供一个字典文件##$ python make_dictpass.py 1 8 1 ipythosd$ python make_dictpass.py nahontchen chenyibfeo ipythoniue coreostche ...$ python make_dictpass.py 1 8 1 ipythosd$ python make_dictpass.py nahontchen chenyibfeo ipythoniue coreostche ...
