We're excited to share with you our newest video, "How to solve KeyError: 'index' when using del df['index'] if 'index' column does not exist. in Python". 🎥 This series is meticulously designed to arm you with knowledge 🧠 and skills 🛠️ to overcome frequent coding challenges.

Today, we will decipher 🔎 and resolve a common error faced by Python coders: the bit hard to solve KeyError: 'index' when using del df['index'] if 'index' column does not exist.. Here is a snapshot of the code of the video:

Troubling Scenario: ❗️

import pandas as pd

df = pd.DataFrame({'A': [1, 2], 'B': [3, 4]})
del df['index']

Unwanted Result: 🚫
