## Python Math: Exercise-66 with Solution

Write a Python program to create an ASCII waveform.

Sample Solution:-

Python Code:

``````from time import sleep
from math import sin, cos, radians

# increase 40 to get more wave
for n in range(1, 40):
circle_1 = 50 * (1 + sin(radians(n*10)))
circle_2 = 50 * (1 + cos(radians(n*10)))
print("#".center(int(circle_1)))
print("*".center(int(circle_2)))
sleep(0.05)
```
```

Sample Output:

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'
```
