Hi!I wrote a simple loop like this: d = {} ... for k in d: if some_condition(d[k]): d.pop(k) If I run this, Python complains that the dictionary size changed during iteration. I understand that the iterator relies on the internal structure not changing, but how would I structure this loop otherwise?
my first thought (untested): use a copy of d for the if clause, then pop from the original. bye -- http://mail.python.org/mailman/listinfo/python-list
