Returning a date as string

[Björn Keil]

Hello pythons,

I have little problem with understanding conversions in python. I've
written a little class - nothing much, just to try out Python a little
- containing the following method:

    def __repr__(self):
        """Serializes the note.

        Currently the format of notes isn't decided upon. XML output
is
        projected."""
        return "Due: " + str(self.dateDue) + \
               "\nDate: " + str(self.dateCreated) + \
               "\nSubject: " + self.subject + \
               "\n" + self.content

The fields "dateDue" and "dateCreated" contain datetime.date objects.
Now when I try to serialize the whole thing:

>>> myNote
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "notes.py", line 81, in __repr__
    return "Due: " + str(self.dateDue) + \
TypeError: cannot concatenate 'str' and 'datetime.date' objects

I tryed different variant before I wrapped "self.dateDue" in a str()
constructor:
I tried to put it in brackets, or call its .isoformat() method.
Nothing works. It still complains that I was trying to concatenate a
string with a date, but I really wanna concatenate a string with a
string!

Could anyone please tell me what I am doing wrong?

Greetings,
Björn
