## Python Math: Exercise-32 with Solution

Write a Python program to print a complex number and its real and imaginary parts.

Sample Solution:-

Python Code:

``````#Initialize a complex number
cn = complex(2,3)
print("Complex Number: ",cn)
print("Complex Number - Real part: ",cn.real)
print("Complex Number - Imaginary part: ",cn.imag)
```
```

Sample Output:

```Complex Number:  (2+3j)
Complex Number - Real part:  2.0
Complex Number - Imaginary part:  3.0
```

## 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'
```
