Why does return not take parentheses like return('stuff') but should only be return 'stuff'

panda.py 
class Panda:
    species = 'Ailuropoda melanoleuca'
    food = 'bamboo'

    def __init__(self, name, age):
        self.is_hungry = True
        self.name = name
        self.age = age

    def eat(self):
        self.is_hungry = False
        return(f'{self.name} eats {self.food}.') and self.food (bamboo)


panda = Panda("Bao Bao", 5)

Parentheses are placed around arguments when calling a function or method, but return is a statement keyword.

In actual practice parentheses around return values would usually be ignored by Python, but the challenge checker is looking specifically for the syntax taught in the course.

Also, the and self.food (bamboo) after the return in the code above isn't needed and will cause an error.

Finally, for best results in challenges, do only what the instructions ask for. Adding additional code (such as the example usage) can potentially confuse the checker and cause false failures.
