How to iterate through dictionary of dictionaries in python -


i want iterate through dictionary of dictionary. want divide values each dict.. e.g., 0.5/0.4, 0.3/0.2, , 0.1/0.1 find max, haven't reached there yet. iteration appreciated.

#!/usr/bin/env python2  dict = {('a', 0.5): ('b', 0.4), ('c', 0.3): ("d", 0.2), ('e', 0.1): ('f', 0.1)}  keys, values in dict:     print "key: %s" % keys     print "values: %f" % values     keys1, values1 in dict[keys]:         print "key1: %s" % keys1         print "values1: %f" % values1

however error:

key: values: 0.500000 traceback (most recent call last):
file "test.py", line 8, in keys1, values1 in dict[keys]: keyerror: 'a'

first rename variable dict d.

this not dictionary of dictionary. dictionary containing tuples key, , values.

for k, v in d.items():     = k[1]     b = v[1]     print(a/b)
