Get list from pandas DataFrame column headers

The groupby function can be used to concatenate data from multiple rows into one field.

Create a Dataframe

import pandas as pd
import numpy as np

#Create a Dictionary of series
d = {'Name': pd.Series(['Alisa','Bobby','Cathrine','Madonna','Rocky','Sebastian','Jaqluine',
   'Rahul','David','Andrew','Ajay','Teresa']),
   'Age': pd.Series([26,27,25,24,31,27,25,33,42,32,51,47]),
   'Score': pd.Series([89,87,67,55,47,72,76,79,44,92,99,69])}
 
#Create a DataFrame
df = pd.DataFrame(d)
df

the resultant dataframe will be

Now lets get the values as a list by doing:

column_names = df.columns.values.tolist()
column_names

the result will be
