Cant able to find mistake in this code...Please help me!


def rental_car_cost(days):
    price = int(days*40)
    if (days >= 7):
        return price-50
    elif (days <7 & days >=3):
        return price-20
    elif (days<3):
        return price
        return 0
days = raw_input("Enter number of days:")


This is the problem, there is a difference between a parameter and a variable.

days = raw_input("Enter number of days:")

What is a parameter? A parameter is a special kind of variable, used in a subroutine to refer to one of the pieces of data provided as input to the subroutine.

What is a variable? A variable is a value that can change, depending on conditions or on information passed to the program.


Thank you bandit. i am still unclear...tried to read couple of times and understood that I gave parameter but don't know what to do now. Can you explain lil brief please!


Finally figured it out as "&" operator issue. Used "and" in that place and it worked!
