#遍历字典
operator_dict = {'<':'less than' ,'==':'equal'}
print('Here is the original dict:')
(operator_dict)
for i in sorted(operator_dict):
print(f"Operator {i} means {operator_dict[i]}.")
operator_dict['>'] = 'greater than'
print()
print('The dict was changed to:')
for i in sorted(operator_dict):
print(f"Operator {i} means {operator_dict[i]}.")
新增一个知识点，输出的时候使用f""里面能直接使用索引输出字典的键和值。
