1.已知字典('k0':1,'k1': 2,'k2: 3,'k3': 4,'k4: 5.k5':6,'k6': 7,'k7': 8, “k8:9,k9:10},请把字典中value值大于5的键值对打印输出。 2.将题目1中的value值是偶数的统一修改为-1 用python代码

1. 打印字典中value值大于5的键值对:
```
# 定义字典
my_dict = {'k0': 1, 'k1': 2, 'k2': 3, 'k3': 4, 'k4': 5, 'k5': 6, 'k6': 7, 'k7': 8, 'k8': 9, 'k9': 10}
# 遍历字典,判断value是否大于5
for k, v in my_dict.items():
if v > 5:
print(f"{k}: {v}")
```
输出结果:
```
k5: 6
k6: 7
k7: 8
k8: 9
k9: 10
```
2. 将题目1中value值是偶数的统一修改为-1:
```
# 定义字典
my_dict = {'k0': 1, 'k1': 2, 'k2': 3, 'k3': 4, 'k4': 5, 'k5': 6, 'k6': 7, 'k7': 8, 'k8': 9, 'k9': 10}
# 遍历字典,判断value是否为偶数
for k, v in my_dict.items():
if v % 2 == 0:
my_dict[k] = -1
# 打印修改后的字典
print(my_dict)
```
输出结果:
```
{'k0': 1, 'k1': -1, 'k2': 3, 'k3': -1, 'k4': 5, 'k5': -1, 'k6': 7, 'k7': -1, 'k8': 9, 'k9': -1}
```

已知字典('k0':1,'k1': 2,'k2: 3,'k3': 4,'k4: 5.k5':6,'k6': 7,'k7': 8, “k8:9,k9:10},请把字典中value值大于5的键值对打印输出。用python代码
。好的,你的问题已经记录下来了。请看以下 Python 代码:
```
my_dict = {'k0':1,'k1':2,'k2':3,'k3':4,'k4':5,'k5':6,'k6':7,'k7':8,'k8':9,'k9':10}
for key, value in my_dict.items():
if value > 5:
print(key, value)
```
上面的代码会遍历字典 `my_dict` 中的每一项,如果某个键值对的 value 值大于 5,就打印出来。输出结果如下:
```
k5 6
k6 7
k7 8
k8 9
k9 10
```
写一个Python代码,已知字典{'k0': 1, 'k1': 2, 'k2': 3, 'k3': 4, 'k4': 5, 'k5': 6, 'k6': 7, 'k7': 8, 'k8': 9, 'k9': 10},请把字典中value值大于5的键值对打印输出
好的,下面是Python代码:
```
my_dict = {'k0': 1, 'k1': 2, 'k2': 3, 'k3': 4, 'k4': 5, 'k5': 6, 'k6': 7, 'k7': 8, 'k8': 9, 'k9': 10}
for key, value in my_dict.items():
if value > 5:
print(key, value)
```
执行结果:
```
k6 7
k7 8
k8 9
k9 10
```
