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
