Nonetype object is not iterable

Python is a popular and versatile programming language, but like any other language, it can throw errors that can be frustrating to debug. This error is raised because None is not iterable, meaning you cannot loop through it like you can with lists, tuples, or other iterable objects. One of the most common scenarios leading to this error is a missing return statement in a function. To fix this error, make sure our function returns the expected value. Another scenario where you might encounter this error is when working with APIs. To handle this situation, we should check the API response before attempting to iterate over it. If the status code is not , it means there was an issue with the API request. In this case, we return an empty list [] as a placeholder value instead of None. This scenario is straightforward and common. It occurs when we attempt to loop iterate over a variable that has the value None:.

This can help ensure that only objects that have a value are iterated over, which avoids the error. Here, a check is performed to ensure that mylist is not None before it is iterated over, which helps avoid the error. Managing errors and exceptions in your code is challenging.
