Bah, silly me. Scrap that.

Depending on what you want to do, you may consider either:

a.) using del foo[i] if you know i in advance (that is, no looping
required).
b.) use filter(func, foo) to construct a list consist of those elements for
which func returns true (chances to use filter() shouldn't be passed up! :).
c.) use foo.remove("value") to remove the item with the smallest index if
that's suitable for your situation.
