## Python Math: Exercise-10 with Solution

Write a Python program to find the smallest multiple of the first n numbers. Also, display the factors.

Sample Solution:-

Python Code:

``````def smallest_multiple(n):
if (n<=2):
return n
i = n * 2
factors = [number  for number in range(n, 1, -1) if number * 2 > n]
print(factors)

while True:
for a in factors:
if i % a != 0:
i += n
break
if (a == factors[-1] and i % a == 0):
return i

print(smallest_multiple(13))
print(smallest_multiple(11))
print(smallest_multiple(2))
print(smallest_multiple(1))
```
```

Sample Output:

```[13, 12, 11, 10, 9, 8, 7]
360360
[11, 10, 9, 8, 7, 6]
27720

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'
```
