Question

two part question - answered in Python 3

2). Decision Structure: A travel agency is checking whether its tours are good for customers. It follows the table below to label each tour. (e.g., if a tour has 6 destinations and its price is $600, then it should be labelled as ‘expensive’.)

Number of Destinations	Price	Label
<5	<300 or >=300	good or expensive
>=5	<500 or >=500	Good or Expensive

Write a program that asks the user to enter the number of destinations in a tour and the price of this tour. The program should display the label for this tour.

3). Repetition Structure: Note: this question is based on question 2), feel free to add the loops directly into the code for question 2) if you want. a). Add a validation loop for question 2). The validation loop should verify that the user’s input for the number of destinations is a positive number, otherwise it should display an error message and ask for another input. b). Add a loop for question 2) so that the program repeats when the user wants to check another tour. (In other words, the program should ask the user whether he/she wants to check another tour after labeling a tour; if the user answers ‘yes’, the program should again prompt the user to enter the number of destinations and price, and display the corresponding label.)

Part 2) and 3) Sample input & output:

(Prompt) Enter the number of destinations: (User enter) 3

(Prompt) Enter the price for the tour: (User enter) 500

(Output) The label of this tour is Expensive (Prompt) Do you want to check another tour? Enter yes if you do: (User enter) yes

(Prompt) Enter the number of destinations: (User enter) -1

(Output) Please enter a positive number of destinations.

(Prompt) Enter the number of destinations: (User enter) 6

(Prompt) Enter the price for the tour: (User enter) 450

(Output) The label of this tour is Good

(Prompt) Do you want to check another tour? Enter yes if you do: (User enter) no

Answer 1

1)

input code:

"'take user input' while True: n=int(input("Enter the number of destinations:")) ""'check price is valid or not''.. if(n)=0): break else: print("Please enter a positive number of destinations") "''take a loop' while True: "''take input''. price=float(input("Enter the price for the tour:")) 'check price is valid or not if(price>=0); break else: print("Please enter a positive number of price") '"'check for number of destinations"" if n<5: ''check the price!!! if price<300: "''print this if above is True!!! print("good") else: "''else print this'' print("expensiv") else: if price<500: "''print this if above is True' print("Good") else: ''else print' print("Expensiv")

output:

Enter the number of destinations: 5 5 Enter the price for the tour:300 Good ... Program finished with exit code 0 Press ENTER to exit console.

code:

'''take user input'''
while True:
n=int(input("Enter the number of destinations:"))
'''check price is valid or not'''
if(n>=0):
break
else:
print("Please enter a positive number of destinations")
'''take a loop'''
while True:
'''take input'''
price=float(input("Enter the price for the tour:"))
'''check price is valid or not'''
if(price>=0):
break
else:
print("Please enter a positive number of price")
'''check for number of destinations'''
if n<5:
'''check the price'''
if price<300:
'''print this if above is True'''
print("good")
else:
'''else print this'''
print("expensiv")
else:
if price<500:
'''print this if above is True'''
print("Good")
else:
'''else print'''
print("Expensiv")

input code:

i=1 while i==1: 'take user input'. while True: n=int(input("Enter the number of destinations:")) "''check price is valid or not''. if(n>=0); break else: print("Please enter a positive number of destinations") "'take a loop'' while True: "''take input price=float(input("Enter the price for the tour:")) ""'check price is valid or not''. if(price >=0): break else: print("Please enter a positive number of price") "'check for number of destinations' if n<5: "'check the price'' if price<300: "''print this if above is True'' print("The label of this tour is Good") else: "''else print this'' print("The label of this tour is Expensive") else: if price<500: "''print this if above is True' print("The label of this tour is Good") else: "''else print' print("The label of this tour is Expensive") "''ask for run again or not take input' again=input("Do you want to check another tour? Enter yes if you do:") if again.upper( )=='NO' or again.lower( )=='no': i=0

output:

Enter the number of destinations:3 Enter the price for the tour:500 The label of this tour is Expensive Do you want to check another tour? Enter yes if you do: yes Enter the number of destinations:-1 Please enter a positive number of destinations Enter the number of destinations: 6 Enter the price for the tour:450 The label of this tour is Good Do you want to check another tour? Enter yes if you do: no ...Program finished with exit code 0 Press ENTER to exit console
