SUPyF Objects and Classes - 01. Distance Between Points

Problem:
1.  Distance Between Points
Write a method to calculate the distance between two points p1 {x1, y1} and p2 {x2, y2}.
Write a program to read two points (given as two integers) and print the Euclidean distance between them.
Result, needs to be formatted with :.3f

Examples:
Input: |Output:|/    Input: |Output:|/    Input:  |Output: |/
3 4    |5.000  |/    3 4    |2.000  |/    8 -2    |11.402  |/
6 8    |       |/    5 4    |       |/    -1 5    |        |/
