Because Python is not C and doesn't require declarations. > Is there a way to force the scoping? It is scoped. txt is local to the function test. What more do you want? If your functions are so large that you worry about name clashes between code in different parts of the one function, the solution is to break this one huge function into many small functions. That's what functions are for: to encapsulate a limited amount of reusable functionality into a namespace. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
