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]}.')
