Awesome stuff. I will go through your catalogue when I have time. Can I link your videos in my future videos (reference them) when I need some stuff you teach here? I want to help your channel and also save my time by sending people to your channel instead of making the same video as you already have.

why did we give n_neighbors = 3 there?

First of all, thank you for your videos and sharing your knowledge on python, etc. !

load_breast_cancer is a <class 'sklearn.utils._bunch.Bunch'>
Would you recommend the use of sklearn.bunch structures to build dataset for science and apply machine learning?
When is it appropriate to use dataframe vs such data structures ?
A video about choice of data format/structure would be great...
A video about creating a sklearn.bunch (although I can dig on the web...) ?

How can I create my own data (like cancer data in the video)?

In clf.predict can we just predict only one thing's target at a time Or is it the case for KNN.
Plus when I did predict for a single value it showed [0] i.e. an array you said at last it would show malignant Or benign did I do something wrong?
