Is There Any Difference Between Scikit-Learn and Sklearn?

The project was originally started back in 2007 as part of the Google Summer of Code while the first public release was made in early 2010. Additionally, it provides tools for model development, selection and evaluation as well as many other utilities including data pre-processing functionality. More specifically, scikit-learn's main functionality includes classification, regression, clustering, dimensionality reduction, model selection and pre-processing.
