Slice DataFrame with MultiIndex in Pandas

Pandas: Advanced Indexing and Slicing Exercise-4 with Solution

Slice DataFrame with MultiIndex:

Write a Pandas program to slice DataFrame based on MultiIndex levels.

Sample Solution :

Python Code :

import pandas as pd

# Create a DataFrame
df = pd.DataFrame({
    'A': [1, 6, 8, 3, 7],
    'B': [5, 2, 9, 4, 1],
    'C': ['one', 'one', 'two', 'two', 'one']
})

# Set MultiIndex
df = df.set_index(['C', 'A'])

# Slice DataFrame
result = df.loc['one']
print(result)

Output:

     B
A   
1  5
6  2
7  1

Explanation:

• Import pandas library.
• Create a DataFrame.
• Set a MultiIndex using columns 'C' and 'A'.
• Slice DataFrame for index level 'one'.
• Print the results.
