As an exercise, perhaps you might try and see for yourself what the answer to the above question is. > > >> 2) Turn off the preprocessor before chunks of Numpy code: "preparse >> (False)". > > --In such a case, wouldn't you need 'preparse(True)' to turn it back > on?

Global (and again, you could figure out the answer as a simple exercise). > Since cells (in notebook) > can be executed independently, what if, say, a cell with no 'preparse > ()' command is located right after (below) a cell with 'preparse > (False)' but the user re-executes a cell far below which has 'preparse > (True)' in it, then goes back and re-executes the cell in question > (which has no 'preparse')?

You should try it out for yourself. :-) I don't think any of this behavior has changed in the last few years. > > > > > -- William Stein Associate Professor of Mathematics University of Washington http://wstein.org --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
