How to I get the exception message as string in GUI

[fowlertrainer]

Hello ,

I want to get the exception error msg in string, but I don't want to
save to file, or print.
I want to show it in memo.

How to I do it ?

gd=GTMain.GameDatas
s=self.Msg
log="Log:\nStart loading"
s.SetLabel(log)
try:
gd.LoadGamesDatas()
log=log+"\nGame datas succesfully loaded."
except:
import traceback
traceback.print_exc() <--------- what I must write ?
log=log+"\An error occured while loading !"
s.SetLabel(log)

Thanx.
