## Python Math: Exercise-72 with Solution

Write a Python program to create a range for floating numbers.

Sample Solution:-

Python Code:

``````#https://gist.github.com/axelpale/3e780ebdde4d99cbb69ffe8b1eada92c
def frange(x, y, jump=1.0):
i = 0.0
x = float(x)  # Prevent yielding integers.
y = float(y)  # Comparison converts y to float every time otherwise.
x0 = x
epsilon = jump / 2.0
yield x  # yield always first value
while x + epsilon < y:
i += 1.0
x = x0 + i * jump
yield x

print(list(frange(0.0, 1.0, 0.1)))
```
```

Sample Output:

```[0.0, 0.1, 0.2, 0.30000000000000004, 0.4, 0.5, 0.6000000000000001, 0.7000000000000001, 0.8, 0.9, 1.0]
```

## Python: Tips of the Day

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'
```
