Choosing between:
list(d) or d.keys() Which is the one obvious way of turning a dictionary into a list? IMO, list(d) is it. Except that, "turning a dictionary into a list" as an English phrase is indeterminate--do you want the keys or the values or both?
Indeed. In particular, I often write
for k in d: ...
and
for k,v in d: ...
and seem to subconsciously expect Python to work out the rest :-) (this is not a feature request...)
Cheers, mwh
