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.

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.
