the module
object referred to by the name "one". Since there is only one instance
of a given module*, the change is indeed reflected everywhere the "one"
module is accessed.
The problem is that argFunc does not modify (or replace) one.myList, as
MRAB said.
* Unless you do something strange like reload() or editing sys.modules
or having module available under different names...or something.

s[0] and s[-1] raise an IndexError if l contains an empty string.
Better something like:
>>> [s[1:-1] for s in l if (s[:1] == s[-1:] == '*')]
Or just the slightly more verbose startswith/endswith version.

name "_builtins_" is not
defined, as it says. You were probably looking for "__builtins__", with
2 underscores on each end, not just 1.
BTW, "__builtins__" is a CPython implementation detail. If you want to
play with built-in objects, you should import the __builtin__

27;s not much of an option! You should
use a regular argument and check len(args) or somesuch. Or, if you must
keep it an "option", do something equivalent for that.
BTW: Checked out optparse? It's bigger and sexier!

That's what itertools.count() is for.

Some other operating systems have similar facilities, e.g. FSEvents on OS X.

x27;t particularly expensive, it would look nicer
to just use self.i and do "self.i == 0" in __call__.
Not that it matters, but this is probably faster than your version, too,
since it saves a method call.
By the way, IIRC Python only looks up double-underscore methods on the
class, not the instance. That's why you had to indirect through self.F.
