Distance between two points?

Question

Python

Good day! The principle of operation of the task is to load an image, set two points on it, and the program displays the distance between them.
What libraries are there for such purposes and in which direction to dig? T.K. I have not encountered such tasks before and have not gone far beyond the web.

Answer 1

Library - pyTwoPointsDistance
PS You are already fucking lazy or stupid. For one simplest formula, you:
- cut a question on a toaster
- demand a library for the sake of a school formula.
Were you all banned at school? Or is it the education of the 2000s in Russia?

Answer 2

A <5, 7>
B <10, 8>
Вектор V = <B.x - A.x, B.y - A.y>
Длина вектора V = sqrt(V.x * V.x + V.y * V.y)
Длина вектора V и есть расстояние между точками A и B
