生成隨機密碼這件事情用python來干確實相當?shù)姆奖?#xff0c;優(yōu)美的string方法加上choice簡直是絕配

make_password.py

###簡單幾行代碼執(zhí)行即可生成記不住的字符串###

##下例基本上就是這個小腳本的所有工作核心了，使用random模塊的choice方法取string模塊生成的字符串##

>>> string.letters

'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'

>>> string.digits

'0123456789'

>>> choice(string.digits)

'4'

>>> choice(string.letters)

'T'

生成一些人似乎能好記一些的密碼(Qs4Wm84q這種密碼似乎除了復制粘貼沒有別的選擇，話說前年我使用shell生成的類似的密碼給ldap做默認密碼，我當時公司就真有員工把這樣的密碼背下來了，現(xiàn)在想想真心是厲害~~~)。

##這樣看起來是比上面的好記一點了吧，但需要提供一個字典文件##
