Question

Please help me with this Python program.

Write a program that takes the plastic identification number from the user and returns information. The program should allow the user to continue using the program until they quit. It should also validate the input and only accept the integers 1-7 as input. All code should be in a function. I suggest the following function structure: printWelcome - prints program information validateUserinput1 to7 - takes user input, validates, and returns valid input main - allows user to continue entering numbers until the user quits, prints information according to user selection. The following information will be helpful: РЕTE PVC HDPE LDPE PP PS OTHER polyethylene terephthalate polyethylene polypropylene polystynene other plastics including acryfic polycarbonate polyactic bers, nylon iberglass high-density polyvinyl chloride low-density polyethylene toys hard packing refrigerater trays cosmetic bags, costume jewellery CD cases vending cups soft drink bottles mineral watec fruite juice trays for sweets, fruit, plastic packing (bubble foil) and food foils crushed bottles shopping bags highly resistant sacks and most of the wrappings furniture cleaning agents aundry detergents bleaching agents shampoo bottles washing and shower soaps consumers luggage, teys as well as bumpers lining and external berders of the containec cooking oil to wrap the foodstuff cars 1-PET is intended for single use. Reusing increases the risk of carcinogen leaching and bacterial growth. PET is difficult to decontaminate. Recycle but don't reuse 2- HDPE is one of the safest forms of plastic. Resistant to heat and cold. Can be reused and recycled 3-PVC is relatively impervious to sunlight and weather. It contains numerous toxins that can leach throughout the lifecycle of the plastic. Cannot be recycled. Can be reused. 4 LDPE is relatively safe for use. Reusable but not always recyclable. 5 PP is heat-resistant and acts as a barrier against moisture, grease, and chemicals. Can be reused and recycled. 6 PS is inexpensive and lightweight. Leaches carcinogens and breaks up easily. Low market for recycling and difficult to reuse. Should be avoided. 7-PC and "other plastics. These vary which is confusing for consumers. Because of concerns with carcinogen leaching, avoid these unless it also contains the letters PLA or Compostable. These are made from bio-based polymers that can be composted.

Answer is after the screenshot of the output

ANSWER:

#function which prints welcome message

def printWelcome():

    print("Welcome to the plastic identification program!")

    print("Enter plastic identification number and get it's information")

#takes input and returns it

def validateUserInput1to7():

    n=int(input("Enter the plastic identification number: "))

    #if the number is invaid call the function again(recursive calls until the input is valid)

    if n<1 or n>7:

        print("Inlavid input")

        return validateUserInput1to7()

    return n

#main function

printWelcome()

#infinite loop

while True:

    #get the value of n

    n=validateUserInput1to7()

    #if else block to print output

    if n==1:

        print("PET is intended for single use. Reusing increases the risk of carcinogen leaching and bacterial growth. PET is difficult to decontaminate.Recycle but don't reuse.")

    elif n==2:

        print("HDPE is one of the safest forms of plastic. Resistant to heat and cold. Can be reused and recycled")

    elif n==3:

        print("PVC is relatively impervious  to sunlight and weather. It contains numerous toxins that can leach throughput the lifecycle of the plastic. Cannot be recycled.Can be reused.")

    elif n==4:

        print("LDPE is relatively safe for use. Reusable but not always recyclable")

    elif n==5:

        print("PP is heat-resistant and acts as barrier against moisture, grease and chemicals. Can be reused and recycled")

    elif n==6:

        print("PS is inexpensive and lightweight. Leaches carcinogens and breaks up easily. Low market for recycling and difficult to reuse. Should be avoided.")

    elif n==7:

        print('PC and "other" plastics. These vary which is confusing for the customers. Becase of concerns with carcinogen leaching, avoid these unless it also contains the letters PLA or Compostable. These are made from bio-based polymers that can be composted.')

    #ask the user to enter choice, if input is 1 then break out of the loop

    ch=int(input("Enter choice, 1 to continue, 0 to Quit: "))

    if ch==0:

        break
