Write distance(x1, y1, x2, y2) that returns the straight-line distance between the points (x1, y1) and (x2, y2), rounded to 3 decimal places.
Examples
Input: x1 = 0, y1 = 0, x2 = 3, y2 = 4
Output: 5.0
Input: x1 = 0, y1 = 0, x2 = 1, y2 = 1
Output: 1.414
Input: x1 = 1, y1 = 1, x2 = 1, y2 = 1
Output: 0.0
Constraints
- Coordinates are ints or floats with absolute value at most
10**6
Goals
- Take four parameters and combine them in a formula
- Use `math.sqrt` and round
