Not sure what the exact intent of resizing the dict is...however, if you wish to reduce the overall memory consumption of your python process...i would suggest:
- copy the required contents to a new dict..(use dict comprehension if you can) >>> d2 = dict((k,v) for k,v in d1.items() if <insert your conditions here>) - Assign the old dict name to None >>> d1 = None - do a gc.collect() >>> import gc >>> gc.collect() you should see immediate results on process memory consumption.
