If you test, its oviously (I thin its mentioned somewhere in the docs
too) :

__str__ represents an human-readable version of the object as string for
use
with "print" or formatet string ("%s")
__repr__ should produce a form that can be cut & pasted to construct the
named object.

print "Hello"
Hello

"Hello"
'Hello'

see the difference?
