Hi, While cleaning up some code during Python 2 -> Python 3 porting, I switched some code to use str.format(), I found this behavor: Python 2.7 ========= a = "%s" % "hi" b = "%s" % u"hi" c = u"%s" % "hi" d = "{}".format("hi") e = "{}".format(u"hi") f = u"{}".format("hi") type(a) == str type(b) == unicode type(c) == unicode type(d) == str type(e) == str type(f) == unicode My intuition would lead me to believe that type(b) and type(e) would be the same (unicode), but they are not. The confusion for me is why is type(e) of type str, and not unicode? Can someone clarify this for me? I understand that in Python 3, all these cases are str, so it is not as big a problem there, but I am trying to keep things working on Python 2.7. Thanks. -- Craig
