Hello, Dedicated Coders! 🖥️💡

We're excited to share with you our newest video, "How to solve TypeError: can only concatenate list (not "int") to list 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 TypeError: can only concatenate list (not "int") to list. Here is a snapshot of the code of the video:

Troubling Scenario: ❗️

my_list = [1, 2, 3]
result = my_list + 5

Unwanted Result: 🚫
TypeError: can only concatenate list (not "int") to list

Effective Resolution: ✔️

my_list = [1, 2, 3]
result = [x + 5 for x in my_list]

Desired Output: 🏁
[6, 7, 8]

In this detailed walkthrough, we will illuminate 💡 the underlying cause of this error, and offer a comprehensive explanation: Code1 tries to add an integer to a list directly, causing a TypeError. Code2 correctly uses a list comprehension to add 5 to each element in the list, avoiding the error. 🎯
