Обсуждение: PyGreSQL pg.error Exception

Hi to all!        In the documentation of the PyGreSQL module it is said that a 
pg.error exception is thrown when pg.connect or other pg functions cause an 
error. How can i get the value of the error? I have tried print pg.error in 
the except clause but i get only a _pg.error value...

For example:
try:        db = pg.connect( connection parameters);
except pg.error:        print pg.error;

This prints "_pg.error"...

Thanks in advance for your replies,

Denis

Try this:

try:   db = pg.connect(parameters)
except pg.error, error_message   print error_message

I tend to write the except statement a little
differently to remind me that the first parameter to
except is actually expecting a tuple.  So instead I
generally write:

except (pg.error,), error_message

Yes, that looks ugly.  But two months later I don't
have to look in the info file to see how to call
except.

I hope that is helpful,

Jason
