What is the semantic difference between that code and the same without the "then:"? The normal behaviour of both Python code and human instruction sheets is to proceed to the next instruction if nothing went wrong: 1. Go to the office. 2. Sit down at the desk. 3. Open the third drawer down at your right hand. 4. Take the secret instructions. 5. Read and follow the instructions. -- if something goes wrong, take out your pistol and kill every zombie you find -- If there's no desk in the office, you won't continue to the next steps. But for the normal case, you don't have to say "then". ChrisA -- https://mail.python.org/mailman/listinfo/python-list
