Python 排序,python排序

字典排序的原理就是把字典轉化成可以迭代的list來進行排序
字典排序(複雜):

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:最簡單的按照key來

items = dicts.items() items.sort() 

下面來看一下sorted方法

sorted(...)    sorted(iterable, cmp=None, key=None, reverse=False) --> new sorted list
#按照key進行排序 sorted(dict1.items(), key=lambda d: d[0]) #按照value進行排序 sorted(dict1.items(), key=lambda d: d[1])
