Arithmetic Operators in python

Operators        Description                  Example          Calculation                  Output

=                      assignment                  x = 10

==                    equality                       x == y                                                  Is x equal to y

-x         negation        x = -10    y = -x          y == 10

x + y      addition        10 + 11                   21

x - y      subtraction     10 - 11                   - 1

x * y      multiplication 10 * 11                   110

x / y      division       25 / 10                   2.5

x // y     division trunc 25 // 10                   2

                           25// 10.0                  2.0

x % y      modulus        25 % 10                   5 (remainder)

                           25 % 7                     4 (remainder)

X ** y     exponentiation 10 ** 2                    100 (== 10² )

Suggested template PLEASE modify as needed :

fee = 0.0        # initialize  

f1 = 5.0         # table 1 fee

f2 = 4.0         # table 2 fee

f3 = 2.0         # table 3 fee

m = int(input(" Please enter number of minutes parked..."))

if (0 < m and m <= 60 ):          #table 1 minutes

  #  hrs = int(m/60) + 1          # FYI only 

    fee = f1

    print("Parking fee for ", m, " minutes is $", fee)

# now for table 2

elif (m > 60 and m <= 300):       # table 2

    # calculations needed

    print('we are in table 2 fee is ', fee)

elif ( m > 300):                  # table 3 

    #calculations needed

    print('we are in table 3 fee == ', fee)

else:

    print("error  negative minutes", m )

OUTPUT

Please enter number of minutes parked...195

we are in table 2 fee is 0.0

Algorithm :

Input: minutes parked

Output: Parking fee

Your program should ask the user for minutes parked, use the various functions/operators as needed to determine in which table 1, 2 3 the minutes falls into, compute and output the parking fee

Let m = minutes parked

fee = parking fee

Please make sure your code uses the constants: f1 f2 f3

Once you have determined your algorithm, try it for several of the minute examples provided in the tables above for accuracy

Thanks for the question.

Below is the code you will be needing  Let me know if you have any doubts or if you need anything to change.

Thank You !!

    print('we are in table 2 fee is ', fee)
elif (m > 300):  # table 3
    # calculations needed
    fee = f3
    print('we are in table 3 fee == ', fee)
else:
    print("Error: negative minutes", m,'entered')
