输出字典fruits中键值最大的键值对。完善代码。 fruits = {"apple":10,"mango":12,"durian":20,"banana":5} m = 'apple' for key in fruits.keys(): #此段代码请完善 print('{}:{}'.format(m,fruits[m]))

可以通过以下代码实现:
```python
fruits = {"apple":10,"mango":12,"durian":20,"banana":5}
max_key = max(fruits, key=fruits.get)
print('{}:{}'.format(max_key, fruits[max_key]))
```
输出结果为:
```
durian:20
```
解释:使用 `max` 函数找出字典 `fruits` 中值最大的键,然后通过 `{}` 占位符和 `format` 方法输出键值对。

描述 输出字典fruits中键值最大的键值对。完善代码。 fruits = {"apple":10,"mango":12,"durian":20,"banana":5} m = 'apple' for key in fruits.keys(): #此段代码请完善 print('{}:{}'.format(m,fruits[m]))
以下是完整代码:
```python
fruits = {"apple":10,"mango":12,"durian":20,"banana":5}
m = 'apple'
for key in fruits.keys():
if fruits[key] > fruits[m]:
m = key
print('{}:{}'.format(m, fruits[m]))
```
该代码首先定义了一个字典 fruits,其中每个键表示一种水果,对应的值表示该水果的数量。然后,定义了一个变量 m,初始值为 'apple',表示要查找的最大值对应的键。
接下来,使用 for 循环遍历字典 fruits 的所有键。在循环中,使用 if 语句判断当前键所对应的值是否大于 m 所对应的值,如果是,则将 m 更新为当前键。这样,循环结束后,变量 m 就存储了字典 fruits 中值最大的键。
最后,使用 format() 方法将 m 和对应的值输出,输出格式为 "键:值"。运行该代码,输出结果为 "durian:20",表示字典 fruits 中键值最大的键值对是 "durian:20"。
