I should add another difference in the behaviour of variables import in one or the other way. This can lead to subtle differences.
If you use 'from module import x, y' (or 'from module import *') Python makes new `bindings' of the names `x' and `y' in the importing module with the values these names had in the imported module. However they are independent of the original ones. So if you execute an assignment to x in the original module, e.g. in a function that was defined there and that you also imported, the change in x is not reflected in the imported x, and vice versa. This can lead to unexpected behaviour. If, however, you say 'import module' and then use module.x, then it is the same variable, and changes in the imported module's x will be visible in the importing module's module.x and vice versa. -- Piet van Oostrum <[EMAIL PROTECTED]> URL: http://www.cs.uu.nl/~piet [PGP 8DAE142BE17999C4] Private email: [EMAIL PROTECTED] _______________________________________________ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig
