Your code so far

def apply_discount (price,discount):
    if not isinstance(price,(int,float)):
        return ("The price should not be a number")
    if not isinstance(discount,(int,float)):
        return ("The discount should not be a number")
    if price <= 0:
        return ("The price should be greater than 0")
    if  not 0 <= discount >= 100:
        return ("The discount should be between 0 and 100")
    
    discount_amount = price * (discount / 100)
    final_price = price - discount_amount
    return final_price

Welcome to the forum @shaikh.ayaan !

Check the messages you are returning for the first two validations.

Also, what do you see printed when you test, as follows:

print(apply_discount(100,20))
print(apply_discount(200,50))
print(apply_discount(50,0))
print(apply_discount(1,100))
print(apply_discount(74.5,20))
