Traversing Data

We calculated the distances between two places. However, we need to calculate the distances between all locations to be able to calculate the shortest total distance. Since we don’t want to repeat the previous step manually for all locations, we’ll solve it via a loop instead.

Distance between all locations

To get started, let’s first calculate the distance between three stores: A, B, and C. With islice, we iterate over the df.iterrows() iterable, which starts at counterFixed. Using df.index != i, we ensure that the distance from any store to itself is not calculated.
