Hello, Dedicated Coders! 🖥️💡

We're excited to share with you our newest video, "How to solve KeyError: 'Column does not exist in DataFrame' 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 does not exist in DataFrame'. Here is a snapshot of the code of the video:

Troubling Scenario: ❗️

import pandas as pd

data = {'A': [1, 2, 3], 'B': [4, 5, 6]}
df = pd.DataFrame(data)
print(df['C'])

Unwanted Result: 🚫
KeyError: 'Column does not exist in DataFrame'

Effective Resolution: ✔️

import pandas as pd

data = {'A': [1, 2, 3], 'B': [4, 5, 6]}
df = pd.DataFrame(data)
print(df['B'])

Desired Output: 🏁
0 4
1 5
2 6
Name: B, dtype: int64

In this detailed walkthrough, we will illuminate 💡 the underlying cause of this error, and offer a comprehensive explanation: In Code1, the KeyError occurs because column 'C' does not exist in the DataFrame. To fix this, replace 'C' with an existing column name like 'A' or 'B' when printing. 🎯
