Because I did not want to expose my passwords in plain text whenever an exception was thrown or inside the debugger, I wrote this simple snippet. It's very simple, but can be quite useful nonetheless...
Python, 3 lines

Copy to clipboard1 2 3 | class passwd(str):
def __repr__(self):
return repr('*' * self.__len__())
|
To demonstrate its use, here some examples:
>>> astr = 'aString'
>>> astr
'aString'
>>> print astr
aString
>>> apwd = passwd('aPassword')
>>> apwd
'*********'
>>> apwd == 'aPassword'
True
>>> print apwd
aPassword
More important, the password string will not immediately show up in your debugger in plain text or in exception frames, since __repr__ is used for those cases.
Nice! Although I'd write it as:
Yep, that's a better version. I'll be using that one myself from now on... Thanks!
I like the simplicity of the code. Very useful. However I don't see why you have to reveal the length of your password. Why not use 8 * '*' for example.
