TypeError: 'type' object is not iterable

This error occurs when you try to iterate over an object that is not iterable. In Python, an iterable is any object that can return an iterator, which can be used to loop over its contents.

For example, you can iterate over a list, tuple, set, or dictionary in Python, but you cannot iterate over an integer or a string.

Here is an example of code that can cause this error:

my_object = int
for item in my_object:
    print(item)

In this case, `my_object` is an integer, which is not iterable. Therefore, you cannot loop over its contents, and Python raises a `TypeError` when you try to do so.

To fix this error, you need to make sure that the object you are trying to iterate over is actually iterable. If it is not, you may need to convert it to an iterable object first.
