## Python Math: Exercise-29 with Solution

Write a Python program to calculate wind chill index.

Sample Solution:-

Python Code:

``````import math
v = float(input("Input wind speed in kilometers/hour: "))
t = float(input("Input air temperature in degrees Celsius: "))
wci = 13.12 + 0.6215*t -  11.37*math.pow(v, 0.16) + 0.3965*t*math.pow(v, 0.16)
print("The wind chill index is", int(round(wci, 0)))
```
```

Sample Output:

```Input wind speed in kilometers/hour: 120
Input air temperature in degrees Celsius: 35
The wind chill index is 40
```

## 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'
```
