+

+> Data Science is an ever-growing field, there are numerous tools & techniques to remember. It is not possible for anyone to remember all these functions, operations and formulas for each of concept. **That’s why we have cheat sheets and summaries**. They help us access the most commonly needed reminders for making our Data Science journey fast and easy.

+

+> There are thousands of cheat sheets available out there. However, how many of them do you really find useful ?

+>

+> It’s a treasure to have good quality resources compiled at one place. Hence, I decided to go ahead and put in this end to end compilation of Cheat Sheets for an instant and thorough reference.

+

+**_For my readers’ convenience, I have segregated the best cheat sheets (comprehensive yet concise) separately for each of the below topics. . ._**

+

+1. **_Python_** (_Basic python as well as ML libraries : Numpy /Pandas/Matplotlib/Seaborn/Plotly/Spacy_)

+2. **_R_**

+3. **_SQL_**

+4. **_Web scraping Tools_** (_Beautifulsoup, Scrapy and Selenium)_

+5. **_Data Visualization Tools_** (_Tableau, Power BI_)

+6. **_Maths and Statistics_**

+7. **_Machine Learning Algorithms_** _(Supervised and Unsupervised)_

+8. **_Deep Learning and NLP_** _(Neural Networks, Keras, Tensorflow, Pytorch, NLTK, Spacy)_

+9. **_IDE/OS_** _(GitHub, Linux, SkLearn, Jupyter Notebook)_

+

+**Final Thoughts**

+So that was my effort in segregating and collecting the best cheat sheets on various Data Science facets. I hope it helps and will keep updating this blog with newer and better cheat sheets.

+

+Please feel free to add in your views and suggestions for the same and I promise to keep an eye on each of them and add them to the list above!

+

+Will be soon back with another useful blog on Data Science!

+

+**Till then..**

+Happy Learning!!

+

+Cheers :)
