Pandas index column title or name

To set the name of the index column in a pandas DataFrame, you can use the .rename_axis() method or the .index.name attribute. Here is an example:

set the name of the index column in a pandas DataFrame

import pandas as pd

# Create a sample DataFrame
df = pd.DataFrame({'A': [1, 2, 3], 'B': [4, 5, 6]})

# Method 1: using .rename_axis()
df = df.rename_axis("Index", axis=0)

# Method 2: using .index.name
df.index.name = "Index"

print(df)

<div class="alert alert-info flex not-prose"> <span class="hidden md:block">Watch a video course </span> Python - The Practical Guide</div>

This will set the name of the index column to "Index". You can replace "Index" with any other string to set the desired name.
