Manhattan Distance in Python

 

Manhattan Distance in Python

def manhattan_distance(point1, point2):

    return sum(abs(a - b) for a, b in zip(point1, point2))

point1 = (1, 2)

point2 = (4, 6)

distance = manhattan_distance(point1, point2)

print(f"Manhattan distance: {distance}")

Manhattan distance: 7

Manhattan Distance Using NumPy

import numpy as np

def manhattan_distance_np(point1, point2):

    return np.sum(np.abs(np.array(point1) - np.array(point2)))

# Example usage

point1 = (1, 2)

point2 = (4, 6)

distance = manhattan_distance_np(point1, point2)

print(f"Manhattan distance (NumPy): {distance}")

Manhattan distance (NumPy): 7

Manhattan Distance Using a Custom Loop

def manhattan_distance_loop(point1, point2):

    distance = 0

    for a, b in zip(point1, point2):

        distance += abs(a - b)

    return distance

# Example usage

point1 = (1, 2)

point2 = (4, 6)

distance = manhattan_distance_loop(point1, point2)

print(f"Manhattan distance (Loop): {distance}")

Manhattan distance (Loop): 7

Manhattan Distance Using Map and Lambda

def manhattan_distance_map(point1, point2):

    return sum(map(lambda a, b: abs(a - b), point1, point2))

# Example usage

point1 = (1, 2)

point2 = (4, 6)

distance = manhattan_distance_map(point1, point2)

print(f"Manhattan distance (Map and Lambda): {distance}")

Manhattan distance (Map and Lambda): 7

Manhattan Distance Using a One-Liner Function

manhattan_distance_oneliner = lambda p1, p2: sum(abs(a - b) for a, b in zip(p1, p2))

# Example usage

point1 = (1, 2)

point2 = (4, 6)

distance = manhattan_distance_oneliner(point1, point2)

print(f"Manhattan distance (One-Liner): {distance}")

Manhattan distance (One-Liner): 7

Manhattan Distance Using List Comprehension

def manhattan_distance_listcomp(point1, point2):

    return sum([abs(a - b) for a, b in zip(point1, point2)])

# Example usage

point1 = (1, 2)

point2 = (4, 6)

distance = manhattan_distance_listcomp(point1, point2)

print(f"Manhattan distance (List Comprehension): {distance}")

Manhattan distance (List Comprehension): 7
