I'd like to encode a string in base64, but I found a inconsistent of
two methods:

>>> 'aaa'.encode('base64')
'YWFh\n'
>>> import base64
>>> base64.b64encode('aaa')
'YWFh'
>>>


as you can see, the result of
'aaa'.encode('base64')
has a '\n' at the end, but the other method doesn't.

Why the inconsistent?
Thanks.

Don't know. Does it matter?

>>> import base64
>>> base64.decodestring(base64.b64encode('aaa'))
'aaa'

>>> 'aaa'.encode('base64').decode('base64')
'aaa'

(so far so good, and as expected)

>>> base64.decodestring('aaa'.encode('base64'))
'aaa'

>>> base64.b64encode('aaa').decode('base64')
'aaa'

(As far as I can see, both methods are completely consistent)

Yeah...

>>> import base64
>>> a = 'aaa'.encode('base64')
>>> aa = base64.b64encode('aaa')
>>> a == aa
False

Your notion of 'consistency' is wanting.
