automatic naming of variables to create objects

[r holland]

The only way I know of to create a series of object/variable names in
a loop is to form strings and then use exec (or eval in some cases).
Is there a better way?

Two other options:

import __main__
for name in "foo bar baz".split(): .... setattr(__main__, name, "set using setattr()")
.... foo 'set using setattr()' for name in "foo bar baz".split(): .... globals()[name] = "set using the globals() dictionary"
.... foo 'set using the globals() dictionary' Is there a better way?

class Namespace: pass .... ns = Namespace()
for name in "foo bar baz".split(): .... setattr(ns, name, "make your own namespace")
.... ns.foo 'make your own namespace'

This doesn't pollute the global namespace and reduces the risk of name
clashes.

Thanks for that, Peter.
