• Data
Well. I searched for data to get additional information to the data I already have. Kaggle’s datasets are countless. The tabs in my browser are cumulative when reading the community and the different challenges. I find the datasets :
- WDIData : some development indicators from internatopnal sources.
 - Education Statistics: a collection of indicators that describe education access.
 - 20 years US University Dataset : contains information about universities of United State.
 - USA Airport Dataset: some informations about USA flights
 - US_Perm_Visa: informations about the job of a foreign worker
 - Airline Delay and Cancellation Data: more data about flights
 
I limit the loading of files to 1000 lines while exploring with Python.
I read “La Logique pas a pas”(Logic step by step) by Jacques Duparc, The theory of sets more specifically. I love that book! 
I learn about df.read_ to load files.
Tomorrow, I will work about data clean… or not!
So, step by step and keep learning!
