[New-bugs-announce] [issue11900] 2.7.1 unicode subclasses not calling __str__() for print statement

[Dave Opstad]

New submission from Dave Opstad <dave.opstad at monotypeimaging.com>:

Python 2.7.1 doesn't appear to do the usual implicit call to str() for subclasses of unicode. In the following snippet, I would have expected print myTest and print str(myTest) to behave the same:

>>> class Test(unicode):
...   def __str__(self):
...     print "In __str__"
...     return (u"*** " + self + u" ***").encode('utf-8')
...   def __unicode__(self):
...     print "In __unicode__"
...     return u"*** " + self + u" ***"
... 
>>> myTest = Test(u"abc")
>>> print myTest
abc
>>> print str(myTest)
In __str__
*** abc ***
>>> print unicode(myTest)
In __unicode__
*** abc ***
