## Python3では dict.items(), dict.keys(), dict.values()
for key, value in users.items():
    print("key: %s value: %d" %(key,value))
for key in users.keys():
    print("key: %s" %key)
for value in users.values():
    print("value: %d" %value)




## Python2では dict.iteritems(), dict.iterkeys(), dict.itervalues()

#for key, value in users.iteritems():       # iteration(反復) items
#    print("key: %s value %d" %(key,value))
#for key in users.iterkeys():
#    print("key: %s" %key)
#for value in users.itervalues():
#    print("value %d" %value)
