creating two points (x,y) and adding them together..

[azhag]

Hi,
I have started learning python this week and am trying to write a simple script. I wish to use a function to create two user defined points A and B, each with two coordinates (x, y). I then want to use another function to add the coordinates together (x1+x2, y1+y2)

Here is what i have...

def createPoint(x,y):
    return [x,y]
def additionAB (x1, x2,  y1, y2):
    c = x1 + x2, y1 + y2
    return c;
x1 = input ('Enter a value x of point a')
y1 = input ('Enter a value y of point a')
x2 = input ('Enter a value x of point b')
y2 = input ('Enter a value y of point b')
print (c)

As I'm new here I have no idea what has gone wrong. I wish to keep it as simple as possible and easy to understand. Any help would be greatly appreciated! Thanks in advance

input() returns a str. You will need to convert that to a number.

Wrap any code inside Python tags (there is a button in the editor). If you have an error, post the error and the entire traceback. Wrap error in error tags (another button in the editor).

You probably want this to create the points:

def createPoints():
    x1 = int(input ('Enter a value x of point a '))
    y1 = int(input ('Enter a value y of point a '))
    x2 = int(input ('Enter a value x of point b '))
    y2 = int(input ('Enter a value y of point b '))

    return [[x1, y1], [x2, y2]]

To add the points:

def additionAB (points):
    c = points[0][0] + points[1][0], points[0][1] + points[1][1]
    return c

The call them

print(additionAB(createPoints()))
