In this tutorial, we will look at how to calculate the Manhattan distance between two points in Python with the help of some exmaples. What is Manhattan Distance? Manhattan distance (also called taxicab distance) is the sum of absolute differences between the coordinates of two points. The following image illustrates the computation of Manhattan distance

You can use Pandas groupby to group the underlying data on one or more columns and estimate useful statistics like count, mean, median, std, min, max etc.  Sometimes knowing the first, last, or the nth value in the group might also be useful. In this tutorial we will look at how to get the last value for each group with the help
