大神们，帮忙写写这个代码啊

#!/usr/bin/python3
# -*- coding:utf-8 -*-

summy=0
maxmy=0
maxmykey=""
minmy=10000
minmykey=""

dict = {'交通':40,'保洁': 5,'餐饮':35,'修理':10,'办公用品':15,'水电': 2}
for key in dict:
    print(key+':',dict[key],"万元")
    summy+=dict[key]
    if dict[key]>maxmy:
        maxmy=dict[key]
        maxmykey=key
    if dict[key]<minmy:
        minmy=dict[key]
        minmykey=key   

print("最高金额为 "+maxmykey+',金额:',dict[maxmykey],"万元")
print("最低金额为 "+minmykey+',金额:',dict[minmykey],"万元")
print("总金额为：",summy,"万元")
      

感觉可以，请点赞采纳哦，兄die
