Scikit learn is the library for machine learning which is well documented that a naive machine learning developer can also use it.The algorithms that are implemented in the library are the common machine learning algorithms and they can scale for almost every size of data.You can easily use the machine learning algorithms in a normal python program and take the advantage of the data analytics through ML using scikit learn.

Scikit-learn is a well-documented Python library that gives easy access to many prominent machine learning algorithms. The library is designed in such a way as to have a consistent API regardless of which algorithm you choose to use, so it is easy to pick up and try a new algorithm you have never used before.

The best machine learning library that I have found on the web. It is the library which is used by the experts for machine learning exercises. Using scikit-learn you can easily get your classifier or else regression model developed in a single line and then just train your data through that classifier by passing training data to it and also you can save the trained model and use it in future.You can also customize the famous ML algorithms and tune them according to your usage.
