### Getting input from user

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 ?

Of course this is possible, and of course we can assist you... but...
First we ask that you show us any attempts you have made and clarify exactly where you are having the problem. If the problem is "I haven't done anything and I don't know how to start," then it is likely we can't help.

You can't get multiple inputs on a single line.
You can, however, create multiple values from the string returned by raw_input():

Code: Select all
`>>> user_input = raw_input('Enter your stuff: ')Enter your stuff: 1 2>>> user_input'1 2'>>> user_input.split()['1', '2']>>> a, b = user_input.split()>>> a'1'>>> b'2'>>> int(a)1>>> int(b)2`

Code: Select all
`>>> y=input()1 5>>> y.split()['1', '5']>>> c,d = y.split()>>> import math>>> output=math.sqrt((a-c)**2+(b-d)**2)Traceback (most recent call last):  File "<pyshell#17>", line 1, in <module>    output=math.sqrt((a-c)**2+(b-d)**2)TypeError: unsupported operand type(s) for -: 'str' and 'str'`

I now have a problem that when i split ,the input is not integer so i cannot calculate.

Yes, use int() to convert them to integers.
