## Python Math: Exercise-43 with Solution

Write a Python program to display the fraction instances of the string representation of a number.

Sample Solution:-

Python Code:

``````import fractions

for s in ['0.7', '2.5', '9.32', '7e-1']:
f = fractions.Fraction(s)
print('{0:>4} = {1}'.format(s, f))
```
```

Sample Output:

``` 0.7 = 7/10

2.5 = 5/2

9.32 = 233/25

7e-1 = 7/10
```

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'
```
