Can you not just allocate a dynamically created string to a normal Python list? Thee are valid cases in Python where you do need to preallocate a block of storage and where the array module is the best choice but before going there lets be sure we need to! > Also, how about pointers? Most things in Python are effectively pointers in that all variables in Python are effectively references in C++ terms. There are no static variables. Everything is passed by reference. > I'm using a c++ wrapped in python package > called vtk and there are some function or class "attributes" which > return pointers. How do I create a pointer reference? Its just a name in Python myName = returnMyPointer() HTH, -- Alan Gauld Author of the Learn to Program web site http://www.freenetpages.co.uk/hp/alan.gauld _______________________________________________ Tutor maillist - [email protected] http://mail.python.org/mailman/listinfo/tutor
