使用Python生成随机密码的示例分享
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### $pythonmake_passwd.py DLrw9EiT Qs4Wm84q RQwl4L2L u9g0LgwW jHPtYdyU ...
$pythonmake_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## $pythonmake_dictpass.py181 ipythosd $pythonmake_dictpass.py nahontchen chenyibfeo ipythoniue coreostche ... $pythonmake_dictpass.py181 ipythosd $pythonmake_dictpass.py nahontchen chenyibfeo ipythoniue coreostche ...
