## Python Math: Exercise-79 with Solution

Write a Python program to compute Euclidean distance.

Note: In mathematics, the Euclidean distance or Euclidean metric is the "ordinary" (i.e. straight-line) distance between two points in Euclidean space. With this distance, Euclidean space becomes a metric space. The associated norm is called the Euclidean norm.

Sample Solution:-

Python Code:

``````import math
# Example points in 3-dimensional space...
x = (5, 6, 7)
y = (8, 9, 9)
distance = math.sqrt(sum([(a - b) ** 2 for a, b in zip(x, y)]))
print("Euclidean distance from x to y: ",distance)
```
```

Sample Output:

```Euclidean distance from x to y:  4.69041575982343
```

Python: Use Get() to Retrieve a Value in a Dictionary

```>>> number_dict = {0: 'zero', 1: 'one', 2: 'two', 3: 'three'}
>>> number_dict
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
KeyError: 5
>>> number_dict.get(5, 'five')
'five'
```
