## Python Math: Exercise-15 with Solution

Write a Python program to returns sum of all divisors of a number.

Sample Solution:-

Python Code:

``````def sum_div(number):
divisors = 
for i in range(2, number):
if (number % i)==0:
divisors.append(i)
return sum(divisors)
print(sum_div(8))
print(sum_div(12))
```
```

Sample Output:

```7
16
```

Python: Get the Key Whose Value Is Maximal in a Dictionary

```>>> model_scores = {'model_a': 100, 'model_z': 198, 'model_t': 150}
>>> # workaround
>>> keys, values = list(model_scores.keys()), list(model_scores.values())
>>> keys[values.index(max(values))]
'model_z'
>>> # one-line
>>> max(model_scores, key=model_scores.get)
'model_z'
```
