The ever growing field – Data Science has numerous techniques and tools. It is not possible for anybody to remember all the formulas, operations and functions for each concept. That is why Cheat Sheet. So, I decided to write an article compiled of chosen right cheat sheet on the basis of content, clarity and comprehensiveness.

After filtering numerous sheets, I came up with collection of some cheat sheets on machine learning, python for data science and big data for Python Development. Following are the cheat sheets segregated according to the their topics on tools, techniques, libraries and language.
