Hello, Dedicated Coders! 🖥️💡

We're excited to share with you our newest video, "How to solve 'TypeError: 'NoneType' object is not iterable' when trying to loop through a variable that may be None. 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: 'NoneType' object is not iterable' when trying to loop through a variable that may be None.. Here is a snapshot of the code of the video:

Troubling Scenario: ❗️

my_var = None
for i in my_var:

Unwanted Result: 🚫
'TypeError: 'NoneType' object is not iterable' when trying to loop through a variable that may be None.

Effective Resolution: ✔️

my_var = None
if my_var is not None:
for i in my_var:
print(i)

Desired Output: 🏁

In this detailed walkthrough, we will illuminate 💡 the underlying cause of this error, and offer a comprehensive explanation: In Code1, the error occurs because `my_var` is `None` and not iterable. Code2 corrects this by checking if `my_var` is not `None` before attempting to iterate, preventing the error. 🎯
