Instances as arguments:
You can pass an instance as an argument in the usual way. For example:

def printPoint(p):
   print ’(’ + str(p.x) + ’, ’ + str(p.y) + ’)’
printPoint takes a point as an argument and displays it in the standard format.
If you call printPoint(blank), the output is (3.0, 4.0). Question: Rewrite the distance function from Section 5.2 so

Explanation / Answer

class point:
   x = 0;
   y = 0;
   def printPoint(p):
       print '(' + str(p.x) + ',' + str(p.y) + ')';

from math import sqrt;
def distance(p1,p2):
   result = sqrt(((p1.x-p2.x)*(p1.x-p2.x))+((p1.x-p2.x)*(p1.x-p2.x)));
   print result;

p1 = point();
p2 = point();
p1.y = 12;
p2.x = 5;
p2.y = 7;
distance(p1,p2);
raw_input();
