On Hyperskill, we sometimes need to check that the student's code doesn't use a particular method. For instance, when the task is to manually implement the factorial computation instead of using the factorial() function from the math module. How could we do that?
It is straightforward. We can override math.factorial() to do something else — raise an error or print a message to the student. To do so, first, we define a function that does what we want (for example, prints a message) with the same arguments (since we want to disguise our new function as the original one). Then, outside this new function body, we need to assign it to math.factorial this way: math.factorial = new_math_factorial (pay attention to the absence of parentheses). Now, if the student tries to use math.factorial, our custom function will be raised. It happens because when multiple functions with the same name exist, the later one always overrides the prior.
In this task, you are a content creator at Hyperskill. Implement the example with the factorial yourself. Your program should override math.factorial() and make it print the message Don't cheat! instead of calculating a factorial. You don't need to call anything.
