K-Means Clustering in Python: A Practical Guide – Real Python

WebbK-means Clustering is one of unsupervised learning algorithm used when you have unlabeled data. The goal of this algorithm is to find groups of data. It works iterativelly to assign each point to one of K groups based on their feature similarity. Use in real life K-means Clustering is applicable and powerful in many fields.
