Sort a Dictionary key and values list We are given a dictionary with key-value pairs in an unsorted manner where values are an unordered list. We need to create a program that will sort the keys of the dictionary i.e. make it an ordered one and also sort the value list of the dictio...
We can sort the dictionary by key using a sorted() function in Python. It can be used to sort dictionaries by key in ascending order or
当你需要判断一个KEY是否在dict中或者要遍历dict的KEY时,最好的方法是使用关键字in: d = {'a': 1, 'b': 2} if 'c' in d: print True # DO NOT USE if d.has_key('c'): print True for key in d: print key # DO NOT USE for key in d.keys(): print key Python的dict对象是对KEY...
