<In what way does your code behave incorrectly? Include ALL error messages.>
<What do you expect to happen instead?>```python
if x== int:
Define a function is_int that takes a number x as an input.
Have it return True if the number is an integer (as defined above) and False otherwise.
Oops, try again. Your function fails on is_int(-2). It returns False when it should return True.
