Python first complies the file, which will find any syntax errors that you have in your code. If there are any, then it will stop there before executing the resulting compiled code. If the compilation is successful, it will then run the code, where you might have run-time errors, which are code with a proper syntax but errors during execution. -- Burton Samograd -- http://mail.python.org/mailman/listinfo/python-list
