python中输出字典中至最大或最小的项

>>> dict1 = {"c":30, "a":40, "b":80, "d":60}       ## 测试字典
>>> dict1
{'c': 30, 'a': 40, 'b': 80, 'd': 60}
>>> max_value = max(dict1.values())
>>> for i,j in dict1.items():
...     if j == max_value:
...             print(i,j)                         ## 输出值最大的项
...
b 80

>>> dict1 = {"c":30, "a":40, "b":80, "d":20, "e":60}      ## 测试字典
>>> dict1
{'c': 30, 'a': 40, 'b': 80, 'd': 20, 'e': 60}
>>> min_value = min(dict1.values())
>>> min_value
20
>>> for i,j in dict1.items():  
...     if j == min_value:
...             print(i, j)                   ## 输出值最小的项
...
d 20
