How can a data-frame with multiple indices be created?

edit

A data-frame with multiple indices can be created in pandas by passing a list of column names to the index_col parameter of the read_csv method or by using the set_index method.

Here's an example of how to create a data-frame with multiple indices using the read_csv method:

import pandas as pd

# create a sample csv file
with open('data.csv', 'w') as f:
    f.write('col1,col2,col3\n')
    f.write('A,X,1\n')
    f.write('A,Y,2\n')
    f.write('B,X,3\n')
    f.write('B,Y,4\n')

# read data and set multiple indices
df = pd.read_csv('data.csv', index_col=['col1', 'col2'])

# print the data-frame
print(df)

This will output:

          col3
col1 col2     
A    X       1
     Y       2
B    X       3
     Y       4
