I think the parent post's pseudocode example was too simple to show the real benefits and use cases of goto in C. Obviously his simple example was contrived and could easily be solved with proper if tests. Your idea of using a function is correct for python, though, but not for C However, what you say about else clauses gets extremely hairy when you have to deal with multiple nested if statements. The most common use case in C for goto is when you have cleanup code that must run before leaving a function. Since any number of things could happen while processing a function (at any level of the if statement) that would trigger an exit, having a whole bunch of else statements gets very, very tedious and messy. Often involves a lot of code duplication too. Goto is direct and much cleaner and more readable. A function in C wouldn't work for this because of scoping rules. However it's not necessary in python to do any of this, since you can define nested functions that have access to the parent scope. Anytime you need to clean up, just call the nested cleanup function and then return. -- http://mail.python.org/mailman/listinfo/python-list
