# 如果输入的水果价钱比字典中的低,则替换掉,反之则不更新 for i in score:
cost= {'苹果':5.2,'山竹':12.9,'香蕉':2.4,'荔枝':15,'葡萄':9.3,'桂圆':8,'蓝莓':10,'李子':8} print(score[i])
k=input('请输入水果名称:') \ No newline at end of file
v=float(input('请输入水果价钱:'))
if k in cost:# ?补充条件判断:
if v>cost[k]:
cost[k]=v# ?更新价钱
print(k+'降价了,现价'+str(v)+'元')
else:
print(k+'涨价了,我们不买')
else:
cost[k] = v
print(k+'的价钱'+str(v)+'元已上传~')
