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
f842244d79af85b457811091319d85ff  -
$ echo 'snagglefrob' | md5sum
f842244d79af85b457811091319d85ff  -
$ echo "snagglefrob" | md5sum
f842244d79af85b457811091319d85ff  -


$ python
