Question

There are three seating categories at a stadium. Class A seats cost $20, Class B seats cost $15, and Class C seats cost $10. Write a program that asks how many tickets for each class of seats were sold, then displays the amount of income generated from ticket sales.

Answer 1

Answer:

Following are the program to this question:

def calculate_income(num,seat):#defining method calculate_income

   if seat=="A": #defining condition for seat a

       return num * 20 #return value

   if seat=="B": #defining condition for seat b

       return num * 15 #return value

   if seat=="C": #defining condition for seat c

       return num * 10 #return value

def show_income(a,b,c): #defining method show_Income

   sum=a+b+c # add total seats income

   print("Income for A class seats: $",a) #print value

   print("Income for B class seats: $",b) #print value

   print("Income for C class seats: $",c) #print value

   print("Total Income: $",sum) #print value

def main(): # defining main method

   a=int(input("Enter class A seats: ")) #input seats a value

   b=int(input("Enter class B seats: ")) #input seats b value

   c=int(input("Enter class C seats: ")) #input seats c value

   a_income=calculate_income(a,"A")  #call method for seat a

   b_income=calculate_income(b,"B") #call method for seat b

   c_income=calculate_income(c,"C") #call method for seat c

   show_income(a_income,b_income,c_income) # call method show_income for print all seat value

main()

Output:

Enter class A seats: 2

Enter class B seats: 3

Enter class C seats: 2

Income for A class seats: $ 40

Income for B class seats: $ 45

Income for C class seats: $ 20

Total Income: $ 105

Explanation:

The description of the above program can be described as follows:

• In the above python program, three methods "calculate_income, show_income, and the main method" were defined.  
• The method "calculate_income" accepts two-variable "num and seat" as the parameter, inside the method a three if block is used, that calculate all types of seat class rate and returns its value.
• In the "show_income", we add all the seat value in the sum variable and use the print method, that prints all seat cost, and total cost.
• In the main method, we input all seat value from user input and pass into the calculate_income method and collect all the return value, after calculating calculate_income we pass its return value into the show_income method, that prints all value.
