type object is not iterable

This error occurs when you try to iterate over an object that is not iterable. In Python, an object is iterable if it can be used in a for loop or with any other function that expects an iterable, such as the built-in `map()` or `filter()` functions.
For example, you might see this error if you try to iterate over an integer or a boolean value:
```
>>> x = 42
>>> for i in x:
... print(i)
...
TypeError: 'int' object is not iterable
>>> y = True
>>> for i in y:
... print(i)
...
TypeError: 'bool' object is not iterable
```
To fix this error, make sure you are trying to iterate over an iterable object, such as a list, tuple, dictionary, or string. If you are unsure whether an object is iterable, you can use the built-in `isinstance()` function to check:
```
>>> x = 42
>>> isinstance(x, Iterable)
False
>>> y = [1, 2, 3]
>>> isinstance(y, Iterable)
True
```
