How to fix `TypeError` when trying to concatenate list with non-list type us... in Python

Hello, Dedicated Coders! 🖥️💡

We're excited to share with you our newest video, "How to solve `TypeError` when trying to concatenate list with non-list type using `+`, e.g., `list_var = list_var + non_list_var`. 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` when trying to concatenate list with non-list type using `+`, e.g., `list_var = list_var + non_list_var`.. Here is a snapshot of the code of the video:

Troubling Scenario: ❗️

list_var = [1, 2, 3]
non_list_var = "hello"
list_var = list_var + non_list_var

Unwanted Result: 🚫
`TypeError` when trying to concatenate list with non-list type using `+`, e.g., `list_var = list_var + non_list_var`.

Effective Resolution: ✔️

list_var = [1, 2, 3]
non_list_var = "hello"

Desired Output: 🏁
[1, 2, 3, 'hello']

In this detailed walkthrough, we will illuminate 💡 the underlying cause of this error, and offer a comprehensive explanation: Code1 tries to combine a list with a string using '+', causing a TypeError as '+' cannot concatenate list and string directly. Use `.extend()` or convert the string to a list first. 🎯
