How to fix TypeError: 'int' object is not iterable when passing an int in li... in Python

Hello, Dedicated Coders! 🖥️💡

We're excited to share with you our newest video, "How to solve TypeError: 'int' object is not iterable when passing an int in list of lists instead of sublist. 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: 'int' object is not iterable when passing an int in list of lists instead of sublist.. Here is a snapshot of the code of the video:

Troubling Scenario: ❗️

lists = [[1, 2], 3, [4, 5]]
flattened = [item for sublist in lists for item in sublist]

Unwanted Result: 🚫
TypeError: 'int' object is not iterable when passing an int in list of lists instead of sublist.

Effective Resolution: ✔️

lists = [[1, 2], 3, [4, 5]]
flattened = [item for sublist in lists for item in (sublist if isinstance(sublist, list) else [sublist])]

Desired Output: 🏁
[1, 2, 3, 4, 5]

In this detailed walkthrough, we will illuminate 💡 the underlying cause of this error, and offer a comprehensive explanation: Code1 fails because it tries to iterate over integers. Code2 fixes this by wrapping non-list items in a list, ensuring everything is iterable. 🎯
