## Python Math: Exercise-13 with Solution

Write a Python program to find out, if the given number is abundant.
Note: In number theory, an abundant number or excessive number is a number for which the sum of its proper divisors is greater than the number itself. The integer 12 is the first abundant number. Its proper divisors are 1, 2, 3, 4 and 6 for a total of 16.

Sample Solution:-

Python Code:

``````def is_abundant(n):
fctr_sum = sum([fctr for fctr in range(1, n) if n % fctr == 0])
return fctr_sum > n
print(is_abundant(12))
print(is_abundant(13))
```
```

Sample Output:

```True
False
```

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'
```
