Predictive Hacks

Get the unique values and the type of every column of your data in one line of code

With this hack, you can get the unique values and the type of every column so you can have a better understanding of your data.

For this example, we will use the Titanic dataset from Kaggle.

import pandas as pd
import numpy as np



The Code

pd.DataFrame({"values":{col:df[col].unique() for col in df},'type':{col:df[col].dtype for col in df}})

As you can see, the output is a data-frame that has as index the columns of our original data along with a column that contains their unique values and a column that contains their data type.
