If something goes wrong making sense the error message in Option#2 is going to be much harder than Option#1 - where opening the file in write mode, and writing the file are discrete operations. Also Option#2 is going to be far more platform dependent, even shell dependent [Where does "echo" come from? What does "~" mean?]. Do things in discrete steps, and be explicit about what you are doing. Option#2 fails both those requirements. -- http://mail.python.org/mailman/listinfo/python-list
