字典排序的原理就是把字典转化成可以迭代的list来进行排序
字典排序(复杂):
dicts = {"4":{"key1":"a","num":1},
"2":{"key1":"a","num":2},
"3":{"key1":"a","num":3},
"1":{"key1":"a","num":4}}
items = sorted(dicts.items(), key=lambda d: d[1]['num'], reverse=True)
字典:最简单的按照key来
items = dicts.items()
items.sort()
下面来看一下sorted方法
sorted(...)
sorted(iterable, cmp=None, key=None, reverse=False) --> new sorted list
#按照key进行排序
sorted(dict1.items(), key=lambda d: d[0])
#按照value进行排序
sorted(dict1.items(), key=lambda d: d[1])
