遍历字典

严格按照题目要求去做,另外记得字典排序的时候默认是keys排序,获取value的时候可以使用dict.get(key)也可以直接dict[key]。
operators_dict = {'<': 'less than','==': 'equal'} print('Here is the original dict:') for i in sorted(operators_dict.keys()): print(f'Operator {i} means {operators_dict.get(i)}.') operators_dict['>'] = 'greater than' print('') print('The dict was changed to:') for i in sorted(operators_dict): print(f'Operator {i} means {operators_dict[i]}.')
