I've got something like dict1={key1:{key2:[value1, value2, value3]} key2:{key3:[value4, value5, value6]} ...} where each key is represented by a string, and each key2 to keyN a list containing numbers. Now I want to select each value for each list, e.g. print dict1['key1']['key2']['value3'] print dict1['key2']['key3']['value6'] is what I currently do. But I'd like to be able to achieve this with a loop: for k, v in dict1.items(): print k print v[3] or for k, v in dict1.items(): print dict1[k]['value3'] print dict1[k]['value6'] The real situation is more complex, but the same basic pattern. Thanks! A: You can use get() method to get the value from the nested list: >>> for k, v in dict1.items(): ... print(v['key2'][0]) ... value1 value2 value3 Q: Understanding reflection and metaprogramming This question aims to understand the notion of reflection. Why is reflection considered a reflection (plural of reflection, as the word "reflection" is an abstract noun)? Could it not be called "metametacoding"? A: In terms of reflection, it is a "reflection" because reflection is a recursive procedure. It seems to be strange to name metametacoding metametacoding. My proposal is metacontainer. I am speaking to the rulebook, and it says I can decide to see if it is Tiamat, to see if I'm under the same mind as her. Then, I can
