md5 wrongness?

[Ron Johnson]

Why do Python's md5 and GNU md5sum produce differing results?

$ md5sum --version
md5sum (GNU coreutils) 5.97

$ echo snagglefrob | md5sum
f842244d79af85b 457811091319d85 ff -
$ echo 'snagglefrob' | md5sum
f842244d79af85b 457811091319d85 ff -
$ echo "snagglefro b" | md5sum
f842244d79af85b 457811091319d85 ff -

echo inserts a newline, your Python snippet doesn't.

% echo -n "snagglefro b" | md5sum

They don't differ. Try feeding them the same input:

>>import md5
>>md5.new('snag glefrob').hexdi gest()

'9eb2459fcdd9f9 b8a9fef7348bcac 933'

>>md5.new('snag glefrob\n').hex digest()

Or, alternatively:

Thanks to all. I knew there had to be operator error, but I
couldn't figure out where...
