Python | Calculate City Block Distance
City block distance is generally calculated between 2-coordinates of a paired object. It is the summation of absolute difference between 2-coordinates. The city block distance of 2-points a and b with k dimension is mathematically calculated using below formula:
In this article two solution are explained for this problem – one with the Python code and the other one with the use of a predefined method.
array1 = [1, 2, 13, 5]
array2 = [1, 27, 3, 4]
The CityBlock distance between 2 array is: 36
a = [34, 44, 89, 81, 67, 49, 33, 59]
b = [98, 34, 23, 12, 233, 23, 44]
The CityBlock distance between 2 array is: 412
Code: Python scratch code to calculate the distance using the above formula.
The CityBlock distance between 2 arrays is: 36
There is no restriction for the same size of arrays. So, it’s easy to calculate City Block distance between 2-coordinates using above formula but we can calculate the same using predefined method for arrays having 2-dimension or more.
Code: Python code using the predefined method to calculate the distance using the above formula.
