You can use operator.itemgetter for that:
import operator
stats = {'a':1000, 'b':3000, 'c': 100}

...d generating procedure (for sake of simplicity), but accept one or more 32-bit values as the initial state of the PRNG. Similar seeds (e.g. a simple seed of 1 and 2) can cause correlations in weaker PRNGs, resulting in the output having similar properties (such as randomly generated levels being sim...
