Hi,I'm a python beginner.i'd like to know how to get the inputs from user to this simple question

Write a program to find the distance, d, between points A and B

where the positions of A and B are specified by the Cartesian coordination of (x1, y1) and (x2, y2), respectively.

Enter the first point: 1 1

Enter the second point: 5 5

The distance between (1, 1) and (5, 5) is 5.66.

actually the calculation is easy but i don't know how to get the inputs from user

is there anyway to get multiple inputs in one line ?

any one please help, thanks
