Data Wrangling
Data scientists spend 80% of their time convert data into a usable form.
Clean data:handle messy or missed data
Transform and Extract data
Merge,Join and Reshape data
Time series Resampling
3.Data Analysis
Interactive Data Exploration
Rich visualzation
Satistical Modeling
4.python vs R
TIOBE Index
5.Pros and Cons
R+visualization = perfect match
R,Lingua Franca of Statistics(develop by Statistics)
R is slow
Python is multi-purpose language
Python is challenger for either visualization or essential R packages replacement
