Carefully observe the following code:

import pandas as pd
list_of_dict = [
{ 'Name' : 'Sourab' , 'Age' : 35, 'Marks' : 91}, 
{ 'Name' : 'Rohan', 'Age' : 31, 'Marks' : 87} ,
{ 'Name' : ' Shalini', 'Age' : 33, 'Marks' : 78}, 
{ 'Name' : ' Divya' , 'Age' : 23, 'Marks' : 93}
]
df = pd. DataFrame (list_of_dict) 
print (df)

Answer the following:

(i) List the index of the DataFrame df.

(ii) List the column names of DataFrame df.

(i) The index of the DataFrame df will be the default integer index range starting from 0 to the number of rows minus one. In this case, since df is created from a list of dictionaries, the index will be [0, 1, 2, 3].

(ii) The column names of DataFrame df is 'Name', 'Age', 'Marks'.
