record_calls

I'd like you to write a decorator function that will record the number of times a function is called.

Your decorator function should be called record_calls and it'll work like this:

@record_calls
def greet(name="world"):
    """Greet someone by their name."""
    print(f"Hello {name}")

That record_calls-decorated greet function will now have a call_count attribute that keeps track of the number of times it was called:

>>> greet("Trey")
Hello Trey
>>> greet.call_count
1
>>> greet()
Hello world
>>> greet.call_count
2

Decorator functions are functions which accept another function and return a new version of that function to replace it.

So this should be the same thing as what we typed above:

greet = record_calls(greet)

If you haven't ever made a decorator function before, you'll want to look up how to make one.

If you've made a decorator function before, you might want to attempt one of the bonuses.
