Using this function, the code is "compiled". I do not think this function is often used and most python project simply use the interpreter (which do a small translation into byte-code to be faster and check syntax error before running interpretation). > > >> However, you can catch this at some form of outer level.

Using compile() function yes. So yes there is a way to check "syntax error" before executing code (using compile function and exceptions) but it was not standard, nor widely used... It was still a hack for me, but perhaps i misunderstood or misinterpret. -- Pierre-Alain Dorange Moof <http://clarus.chez-alice.fr/> Ce message est sous licence Creative Commons "by-nc-sa-2.0" <http://creativecommons.org/licenses/by-nc-sa/2.0/fr/> -- https://mail.python.org/mailman/listinfo/python-list
