Question

In Python
Create a function called ℎ?????. The function has as arguments a list called ?????? and a list
call center.
• List ?????? contains lists that represent points.
o For example, if ?????? = [[4,2], [3,2], [6,1]], the list [4,2] represents the point with coordinate ? at 4 and y coordinate at 2, and so on for the other lists. Assume that all lists within points contain two numbers (that is, they have x, y coordinates).
• List ?????? contains two numbers that also represent a point.
o For example, ?????? = [3,3] represents the point with coordinate ? at 3 and with coordinate y at 3.
• The function must return the point in points closest to center according to the distance calculated using the
formula: ???????e = | ?2 - ?1| + | ?2 - ?1|
o For example, if ?????? = [[4,2], [3,2], [6,1]] and ?????? = [3,3], then the function must return [3,2]
(note that according to the formula the distance between the points is:

▪ |4 − 3| + |2 − 3| = 2

▪ |3 − 3| + |3 − 3| = 1

▪ |6 − 3| + |1 − 3| = 5

Answer 1

Code:

def hattan(points,center):
    # calculating all the distances between each points and center
    dist = ([abs(item[0]-center[0]) + abs(item[1]-center[1]) for item in points])

    # getting the position of minimum value in the list
    minpos = dist.index(min(dist)) 
    
    return(points[minpos])  # returning points at minimum index

points = [[4,2], [3,2], [6,1]]
center = [3,3]
print('Requied points: ',hattan(points,center))
