Hello, Dedicated Coders! 🖥️💡

We're excited to share with you our newest video, "How to solve KeyError: '['column_name']' not in index 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: '['column_name']' not in index. Here is a snapshot of the code of the video:

Troubling Scenario: ❗️

import pandas as pd
df = pd.DataFrame({'name': ['Alice', 'Bob']})
print(df['column_name'])

Unwanted Result: 🚫
KeyError: '['column_name']' not in index

Effective Resolution: ✔️

import pandas as pd
df = pd.DataFrame({'name': ['Alice', 'Bob']})
print(df['name'])

Desired Output: 🏁
0 Alice
1 Bob
Name: name, dtype: object

In this detailed walkthrough, we will illuminate 💡 the underlying cause of this error, and offer a comprehensive explanation: In Code1, 'column_name' doesn't exist in the DataFrame. It should be 'name' as specified during DataFrame creation. In Code2, 'name' is correctly referenced, so it prints without error. 🎯
