str() or repr()

[tcronj]

Have reasently upgraded to PySQLite 0.5.
I now have to "typecast" returned values to the "string expecting" GUI 
widgets (wxPython).

Afrer reading the explanation, I'm still not clearer wich is better to 
use... str() or repr()

example: self.wxTextCtrl.Setvalue( str(val["typedate"]))
			   ## or  repr(val["typedate"])

	 self.wxTextCtrl.Setvalue( str(val["typefloat"]))
			   ## or  repr(val["typefloat"])



TIA.
