Python Code:

``````def test_prime(n):
if (n==1):
return False
elif (n==2):
return True;
else:
for x in range(2,n):
if(n % x==0):
return False
return True
print(test_prime(9))
```
```

Sample Output:

```False

## Python: Tips of the Day

Creates a dictionary with the same keys as the provided dictionary and values generated by running the provided function for each value

Example:

```def tips_map_values(obj, fn):
ret = {}
for key in obj.keys():
ret[key] = fn(obj[key])
return ret
users = {
'Owen': { 'user': 'Owen', 'age': 29 },
'Eddie': { 'user': 'Eddie', 'age': 15 }
}

print(tips_map_values(users, lambda u : u['age'])) # {'Owen': 29, 'Eddie': 15}
```

Output:

```{'Owen': 29, 'Eddie': 15}
```
