More reduced : ---------------------------------- u=raw_input('Enter calculation:") print eval(u) ---------------------------------- works and compute : 1+2+3+4-1+4*2 2+3.0/2-0.5 Perform better and shorter, but less educationnal of course... -- 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
