以下字典fruits中是某水果店现有的水果报价,假设此水果店又新进了一种水果,将该种水新进的水果及其报价由键盘输入,以逗号分隔,然后输出水果店所有水果及其报价。完善代输入输出示例:示例1 输入:杨桃,15输出: apple:10 mango:12 durian:20 P banana:5杨桃:15示例2 输入:草莓,30输出: apple:10 mango:12 6 durian:20 banana:5草莓:30用python
```
fruits = {'apple': 10, 'mango': 12, 'durian': 20, 'banana': 5}
new_fruit, price = input("请输入新进水果及其报价,以逗号分隔:").split(',')
fruits[new_fruit] = int(price)
for fruit, price in fruits.items():
print(fruit + ':' + str(price), end=' ')
```
运行示例:
```
请输入新进水果及其报价,以逗号分隔:杨桃,15
apple:10 mango:12 durian:20 banana:5 杨桃:15
请输入新进水果及其报价,以逗号分隔:草莓,30
