columns() to get column header names from DataFrame in Pandas

Pandas

We can create one DataFrame by using dictionary or by reading any Excel or reading CSV file. We will display the column names of this dataframe here.

By using columns

import pandas as pd 
my_dict={'NAME':['Ravi','Raju','Alex','Ron','King','Jack'],
         'ID':[1,2,3,4,5,6],
         'MATH':[80,40,70,70,60,30],
         'ENGLISH':[80,70,40,50,60,30]}
my_data = pd.DataFrame(data=my_dict)
print(my_data.columns) # Object

Output

Index(['NAME', 'ID', 'MATH', 'ENGLISH'], dtype='object')

Getting any perticular column

print(my_data.columns[2]) # Math

By using keys()

print(my_data.keys())

Output

Index(['NAME', 'ID', 'MATH', 'ENGLISH'], dtype='object')

By using for loop

for cols in my_data.columns:
  print(cols)

Output

NAME
ID
MATH
ENGLISH

By using list

print(list(my_data.columns))

Output

['NAME', 'ID', 'MATH', 'ENGLISH']

By using tolist()

print(my_data.columns.values.tolist())

Output

['NAME', 'ID', 'MATH', 'ENGLISH']
