This is wrong. The prefix 'u' means that the following string is a Unicode string, nothing more or less. It is a fact for Python 2.x. See http://docs.python.org/reference/lexical_analysis.html#string-literals The % character after the unicode string means "string interpolation", i.e. replacing the placeholders inside the string template on the left. See the String Formatting Operations http://docs.python.org/library/stdtypes.html#string-formatting-operations You will also find the placeholder types there. >> > Krondaj wrote: >> > > what does the u'%s %s' % mean...

But you can use it only when you can be sure that the Python is 2.6 or newer. The command in your __unicode__ method would look like: def __unicode__(self): return u'{0} {1}'.format(self.first_name, self.last_name) The '{0}' is the placeholder for the self.first_name (zero'th argument, the '{1}' is for the first argument (self.last_name), etc. Since Python 2.7 (if I recall correctly) you need not to use the numbers inside: def __unicode__(self): return u'{} {}'.format(self.first_name, self.last_name) You do not want to return only... def __unicode__(self): return (self.first_name, self.last_name) ... because you want the method to return the unicode string representation. Without .format() or without the % the method would return a tuple with the information, not the string.
