Scikit learn is simply wonderful. It abstracts away all the complexities of several machine learning frameworks. Scikit learn provides beautiful one line function calls to really complex functions and the documentation is beautiful. A complete noob can go through their documentation and understand since it is human readable. In addition to top machine learning models ranging from random forest, decision trees and linear regression, they also provide libraries for data preprocessing. You can do data preprocessing, one hot encoding and lots of other things with Scikit Learn.

I love the fact that almost every machine learning algorithm are made easy in the framework it's very easy to use. It has so many functionalities

I like this library because it is super easy to import the library and use the Machine Learning models. To install scikit-learn it is very easy. They have lots of machine learning models such as random forest, xgboost and many more. You don't need to code from scratch. They provide a lot of parameters to tweak the models also which is helpful.
