## Python Math: Exercise-35 with Solution

Write a Python program to convert Polar coordinates to rectangular coordinates.

Sample Solution:-

Python Code:

``````import cmath
cn = complex(3,4)
# get polar coordinates
print("Polar Coordinates: ",cmath.polar(cn))

# polar to rectangular. Format for input is (length, ‹angle in radians›).
#Returns a complex number
cn1 = cmath.rect(2, cmath.pi)
print("Polar to rectangular: ",cn1)
```
```

Sample Output:

```Polar Coordinates:  (5.0, 0.9272952180016122)
Polar to rectangular:  (-2+2.4492935982947064e-16j)
```

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'
```
