 |
|
| Code: | #!/usr/bin/python
import math
def FindClosestPointAboveXAxis(PointList,TargetPoint):
"""Given a list of points and a target point,this function
returns
the list's closest point, and its distance from the
target. It ignores all points with a negative y-coordinate. We
represent points in the plane (or on screen) as a two-valued
tuple of the form (x-coordinate,y-coordinate).***
ClosestPoint=None
for Point in PointList:
if (Point[1]<0):
continue
DistPoint=math.sqrt((TargerPoint[0]-Point[0])**2 +
(TargetPoint[1]-Point[1])**2)
if (ClosestDistance == None or
DistPoint < ClosestDistance):
ClosestPoint=Point
ClosestDistance = DistanceToPoint
if (DistanceToPoint==0):
print "Point found in the list"
break
else:
print "Point not found on the list"
return (ClosestPoint, ClosestDistance) |
this is what i get when running it in a terminal
| Code: | bash-2.05b$ ./ClosestPoint.py
File "./ClosestPoint.py", line 28
^
SyntaxError: invalid token

thanx 
i know its an easy question , and i feel retarded but , i want to learn ... this is a script from Python 2.1 bible ClosestPoint.py |

Try closing the comment with triple quotes instead of triple asterisks.
